What is networking and how can you do it

 Networking Job meets with networks of people who can help you develop your career prospects. You don't have to be a great shooter or the most friendly person in the world to make useful contacts.

Do it step by step. Start with people you know at work and social life. Keep your ears open and listen for information that may work in your favor.

What are the benefits of networking?

Many good works never reach pages on a recruitment website or in a newspaper. They fulfill oral and the higher the position, the more often it happens.

Even if the post is advertised, it helps to meet someone from the new organization who can give you an internal line. They may even interview you, which will always make it a less stressful experience.

Like any other form of social behavior, networks take place according to certain principles:

·         First impressions count - in person, by phone, or by email. Always be sharp.

·         Don't ask for a job directly - the labor market does not work online; it is an opportunity to gather useful information.

·         Give and climb - networks are two-way alternatives; there is no free lunch.

·         Do the basics - check your contacts before you meet them and follow useful contacts or continue.

·         Think of a lateral - try to extend your network beyond your comfort zone or healthy working life.

·         Patience is - join networks for a long time; Don't expect a plum chance during your first meetings.

Build your network

Even if you are not yet involved in the game, you can have many valuable contacts that you have never seen before.

·         School seniors, colleges or universities

·         Distant family members

·         Family of friends

·         Your doctor, lawyer or accountant

·         Former colleagues or bosses

·         Club members or anyone who meets socially

Keep track of whom you meet and what conversation you have: it makes no sense to build a network of contacts that you have forgotten. Also, try to make regular contacts, even if you have not done anything specific. You do not want to be named the person who only contacts you if you are looking for a favor.

Network events and conferences are a great way to build a network if you're not sure where to start. Make sure you know why you are there and what you want and have copies of your resume or some business cards to give you the essential contacts you make.

Do not wait until you lose your job before answering the phone to talk to people in your industry. Even if you are satisfied with your role and the company is in a stable position, there is no certainty about your job. It could be around the corner.

Networking 2.0

If you are unfamiliar with the idea, the network can be alarming. Something for safer people who are still getting the best jobs. But that's not the whole story. People are very much affected by networking as a valuable business tool.

The Internet is a viable option for everyone, and there are many business forums and networking sites where business people can exchange and discuss opinions and information.

Although you can keep a good barrier between your personal and professional online presence, this is a great way to cope with the latest news in your industry, but you can not afford to find a place. Do it to show it to you.

Networking Advantages & Disadvantages

Advantages:

Think about what people you can network with and understand when it may not be beneficial for them to contact each other.

·         Consider short and long-term career plans when meeting people.

·         Meet with a trusted friend or colleague when you start.

·         Take a look at the network courses if you need additional help.

·         Join networking events in your industry and your region.

·         Listen, talk, and ask questions.

·         Follow new contacts by email or social networks after the event.

·         Ask for help only when necessary, and be prepared to offer support when requested.

·         Always thank someone who has offered assistance and keep them informed of your progress.

Disadvantages:

·         Only set up contacts for short term help.

·         Invest your time in contacts that are only for you.

·         Break the trust or share confidential information.

·         Take off the net for nothing.

·         Neglect your network.

Stop contact as soon as someone has helped.

What does it can take to be a system administrator

 System administrators play a vital role in IT departments and organizations as a whole. This is because system administrators are responsible for the development and operation of the entire company network or computer system, from local networks to intranet and internet systems.

If you need a computer or device, it's the system administrator who makes it happen behind the scenes. If problems arise, it is the system administrator who made a mistake. And even if all goes well, this is because the system administrator maintains, evaluates, and improves infrastructure all the time.

What be a system administrator?

Diplomas in computer science or information technology are a starting point for many technology specialists, and this is true for many system administrators, although equivalent experience may replace formal teaching.

For system administrators employed with Microsoft products, a Microsoft Certified System Administrator certification can be a valuable and valuable task. A similar Linux certification is Red Hat RHCT. Cisco Certified Network Associates and Cisco Certified Network Profession-al are also options for technology professionals. Companies that need support for their systems can benefit from hiring a freelance system admin.

Depending on the size of the system administrator organization and the field of activity, it is expected to perform some coding and programming to maintain and troubleshoot the network.

What makes approximately system administrators better than others?

System administrators who are the cream of the crop are the ones who feel comfortable working with a wide variety of people. While some technologies come into the field to work with machines, not people, a system administrator is the point of contact for non-IT departments, which may require a lot of patience. A good system administrator understands that people will come to them with problems and it is likely that users do not have the knowledge base that IT professionals have.

Forward-thinking system administrators are aware of how cloud computing affects their functions. The cloud reduces the demand for on-site maintenance but increases the need for on-site operations and monitoring. Virtualization, security, and other cloud issues are in the eyes of system administrators, and those who want to be the best can develop their skills as technology evolves.

System Administrator Responsibilities

System administrators handle smaller, more detailed tasks that involve an organization's IT infrastructure. Which includes:

 

• system planning

• installation of its components

• support users when they access the system

• fix network or infrastructure issues

• monitor efficiency and errors

• maintenance and installation of security updates and fixes

• working with other IT staff and IT providers

• the strategy for future updates or changes

• plan and implement security protocols

• network security monitoring

• and work with non-IT teams to promote safe practices

The skills required

As with all technology positions, a system administrator should be technologically inclined and able to solve problems, paying attention to detail and organization. A system administrator wants to know a lot about each system component but can put this information into understandable terms for non-IT users who will access the network.

System administrators must be able to manage a high-pressure environment quickly and quickly. There are many moving parts in any configuration of the IT infrastructure. Add regular maintenance and upgrade requirements, as well as emergencies that require IT help as soon as possible, and system administrators are busy people on different days. Some organizations need on-duty work in the event of interruption or other after-hours problems, so system administrators should be prepared for this possibility, depending on the employer.

System administrators must commit to confidentiality. Being responsible for the entire organizational network means having complete access, with a high probability of finding confidential information. 

System administrators need to continually update their knowledge and be up to date with industry trends and forecasts. Technology is evolving rapidly, and as the future of IT becomes present, it is up to the system administrator to take this information and translate it into real-world solutions that help the entire organization at all levels.

What I've found is that while all systems management positions are different, employers often look for people with extensive IT knowledge, but it is also beneficial to have at least one area that is a strong point.

If system administration sounds like somewhat, you would be good at and interested in, great! We look advancing to working with you to find a technology employer that meets your management skills. The Concero Technology group is dedicated to associating technology specialists with the companies that need them, and we work hard to ensure a match for everyone.

AI in Cybersecurity – A Fresh Tool For Hackers

 The crisis created by a sudden increase in automated phishing attacks is undeniable. And this is happening with more convincing content and greater precision through artificial intelligence (AI), machine learning and big data. And while IT managers use AI to improve security, this technology falls into the wrong hands: Hackers?

 

The dawn of the Internet and developments in information technology allow us to trigger an exact solution to complex problems in various fields, from astrophysics and biological systems to automation and precision. In this rapidly evolving world of innovation in a flash, cybersecurity remains the number one concern, especially for companies facing data-rich transformations such as the Internet of Things (IoT).

 

To a large extent, computer security relies on file signatures to detect malware and rule-based systems to detect network anomalies. Protection often comes from a real virus: security experts isolate malicious files and identify unique names that help other systems become alert and immune. The same is true for the rule-based system: rules are set based on the experience of a potentially harmful activity, or systems are blocked to limit any access to remain safe. The problem for these approaches is their sensitive nature. Hackers always find innovative ways to bypass known rules. Before a security expert discovers the violation, it is often too late.

 

Cybersecurity shocked by AI

 

Traditional malware is designed to perform its malicious functions on all devices on which are located. An example is the NotPetya ransomware epidemic, in which hundreds of thousands of computers have been affected in a vell less span of period. This technique works when the hacker's goal is to cause maximum damage. It is not valid if an attacker has a specific target in mind.

 

However, the advent of disruptive technologies such as artificial intelligence means that our devices and applications understand us better. For example, an iPhone X uses AI to detect faces automatically. While this is an exciting feature, it creates a complicated puzzle that can put sensitive data in the wrong hands. Today, hackers use the same technology to develop intelligent malware that can track goals by tracing millions of users.

 

AI: The game-changer in safety

 

Each year, attacks become more personalized and have a higher probability of success. Hackers have even begun to use artificial intelligence to accelerate polymorphic malware, which means that the code changes constantly and becomes unrecognisable. Using advanced tactics, hackers can bypass security to circumvent anti-spam filters and anti-spam filters, promote fantasy language commands, and bypass anomaly detection engines.

 

The proper update is that this info will also be used to protect the infrastructure. What makes AI's cybersecurity unique is its adaptability. Smart cybersecurity does not need to follow specific rules. On the contrary, you can observe trends and learn. Better yet, artificial intelligence can be integrated directly with everyday protection tools, such as spam filters, intruder detection and network fraud, multi-factor authentication and incident response.

 

Artificial intelligence has become a decisive element for cybersecurity. For the success of cyber safety, artificial intelligence can help in several specific areas:

 

Machine learning: artificial intelligence and machine learning (ML) are two different worlds. Machine learning can considered as a subset of AI that is primarily used to improve knowledge. When it comes to improving cybersecurity, it automatically eliminates the lack of skills to prevent cyber attacks. If malware is detected on the network, automatic incident response is sent. In addition, AI-specific robots completely block access to websites. By avoiding such actions, AI improves the security of an organization or an individual on the Internet.

 

Data Analysis: Data is the key to a successful cyber environment. Artificial intelligence has the potential to identify the right data for the best results. With advanced data from these tools, we gain a deeper understanding of the cyber threats that are available and identify proactive threat prevention best practices.

 

A fusion of technical and human approaches: The most powerful security approach combines the power of AI and human intervention. Machine learning is a good example. Artificial intelligence helps break up complex automated processes to detect attacks and respond appropriately. The ultimate challenge, however, is to produce measurable results using methods that can anticipate, detect, analyze, and prevent attacks. By automating key functions through approaches such as machine learning, Security Engineer can focus their attention elsewhere to create a proactive and more reliable data-driven cyber defense plan.

Understand and install Optical Fiber

 What is optical fiber and what are its differences with ADSL?

What is optical fiber?

Fiber optics is the latest technology in Internet access. In practice, it allows the transfer of data at high speed via light. The latter passes through a cable containing glass or plastic son as fine as a hair.

The deployment of the fiber requires the creation of a new, completely independent network, be it the telephone network or the cable. On this network, data can be transmitted quickly over hundreds or even thousands of kilometers.

The development of fiber goes hand in hand with the evolution of uses and the growing needs of individuals (individuals and businesses). It should be noted, however, that the installation of optical fiber is generally observed in densely populated areas. This is mainly due to the costs of deploying such technology.

What are the differences with ADSL?

Focus on the main differences between ADSL and Orange optical fiber: the table below compares the technical characteristics as well as the average download time of music content (10 pieces of 40 MB each), photos (200 in 8 MP 480 MB each), full HD movie (30 GB) and reaction time on online games (latency).

What are the advantages of fiber optics?

Installing fiber optics allows you to enjoy many benefits:

The fiber is more stable than ADSL because insensitive to electromagnetic disturbances

The quality of the connection and the throughput are not conditioned by the distance to the optical connection node

The optical fiber carries data over very long distances without attenuation of the signal

All members of the household can take full advantage of the performance of fiber optics, regardless of their activity (TV, Internet, phone)

Users can enjoy TV up to high definition (subject to compatible hardware)

Optical fiber Jobs offers better flow. Data transfer is 60 times faster than with ADSL 

Affordable rates. A fiber optic subscription is not necessarily more expensive than an ADSL offer and provides a much higher quality

The fiber makes the symmetrical flow possible (upward and downward flows transmitting the data at the same speed).

Deployment of optical fiber: from operator to users

Plant-fiber-optic-1VINCI Energies, through its brand Axians has deployed optical fiber on behalf of large national operators in many regions, such as the Moselle and French cities such as Lille, Toulouse, Bordeaux, the Paris suburbs, and abroad as well as in France. Poland and Germany. Axians also offers a specific offer for operators to connect small and medium-sized businesses to these very high-speed networks. As a result, VINCI Energies is helping to reduce the digital divide and promote ultra-high-speed Internet access for everyone.

Optical fiber: broadband Internet everywhere, for everyone

The high and very high speed connections made it possible to streamline and speed up communications. By transporting the data at the speed of light, on a light signal led in a fiberglass or plastic finer than a hair, the optical fiber allows a flow approximately 100 times higher than the ADSL network! This light signal can carry data over very long distances, almost without loss.

Much faster access to the Internet, the possibility to watch television in HD, multi-connection ... New uses related to the best quality of the bit rate appear and the number of subscribers to a FTTH network has increased by 70% in one year (at 2nd quarter 2013)! For communities, having a broadband connection has even become an issue of attractiveness that can attract residents or make value to a property.

What is Network Security? Definition and Methods

 Network security is a wide-ranging term that encompasses a variety of technologies, devices and processes. In the simplest case, it is a set of instructions and configurations considered to protect the integrity, privacy and accessibility of computer networks and data using software and hardware technologies. Regardless of size, industry or infrastructure, each company needs a certain degree of network security to protect it from the growing threats of the Internet.

The current network architecture is complex and faces a constantly changing threat environment, and attackers always try to find and exploit vulnerabilities. These vulnerabilities can occur in a variety of areas, including devices, data, applications, users and sites. As a result, today many network security tools and applications are used to address individual threats and exploits, as well as regulatory violations. If only a few minutes of inactivity can cause powerful disruptions and massive damage to a company's balance sheet and reputation, it is vital that these protective measures are taken.

Network Security Methods

To fully implement this type of defense, there are a variety of specialized techniques and types of network security that you want to perform. Cisco, a network infrastructure company, uses the following scheme to break down the different types of network security engineer jobs in USA. Although part of it based on product categories, it is a useful way to think about the different ways to protect a network.

·         Access Control: You must be able to block unauthorized users and devices from accessing your network. Users who have access to the network should be able to work only with the limited resources for which they have been authorized.

·         Anti-Malware: Viruses, worms, and Trojans by definition try to spread across a network and may be inactive for days or weeks on infected computers. Your security measures should do everything to prevent the first infection and to eliminate malware that reaches your network.

·         Application security: Insecure applications are often the vectors used by attackers to access their network. You must use hardware, software and security processes to block these applications.

·         Behavior analysis: You must know what normal network behavior looks like to detect security anomalies or vulnerabilities immediately.

·         Data loss prevention: People are inevitably the weakest security link. They must implement technologies and processes to ensure that employees do not intentionally or accidentally send confidential data outside the network.

·         Email security: Phishing is one of the top common ways for attackers to access a network. Email security tools can block incoming and outgoing confidential information.

·         Firewall: Perhaps the ancestors of network security, follow the rules established to allow or deny traffic on the border among your network and the Internet, creating a barrier between your area of ​​trust and the wild west outdoors. They do not exclude the need for a deep defense strategy, but they remain a necessity.

·         Mobile device and wireless device security: Wireless devices have all the potential security vulnerabilities of another networked device, but can connect to a wireless network in almost every other location, requiring additional verification.

·         Network Segmentation: Software-defined segmentation divides network traffic into different classifications and facilitates the application of security policies.

·         Security and Event Management (SIEM) information: These products are designed to automatically gather information from a selection of network tools to offer the data you need to detect and respond to threats.

·         VPN: A tool (typically based on IPsec or SSL) that authenticates communication between a device and a secure network and creates a secure and encrypted "tunnel" over the open Internet.

·         Web security: You need to be able to control the Internet usage of internal employees to prevent web-based threats from using browsers as a source of infection for your network.

VMware Architect: Introduction, Definition, Advantages, and Responsibilities

Introduction of VMware
VMware is a California-based company founded in 1998 that is developing a virtualization platform for IT infrastructure. VMware is known for its vSphere VMware hypervisor. The VMware hypervisor enables virtualization for all VMware architecture. VMware software developed by IT professionals in five different areas in 1998. VMware advances various types of virtualization application software and is today a leading provider of virtualization software.
VMware officially launched its first product, "VMware Workstation" around 1999. Later, they came with the server application "VMware GSX Server" in 2001 on the market. Since then, additional products have added to the stock. Their products are divided into two types.
·         System Applications
·         Server Application
System Applications: Some of VMware's desktop applications include Horizon Apps, Horizon 7, Horizon cloud, Horizon FLEX on Microsoft Azure, Horizon Infrastructure with Hosted Cloud, and more.
Server Applications: Some server-side application software is Rails, Microsoft .NET Framework, Microsoft IIS with .NET Framework on Windows Server, JBoss for Windows and Linux, vFabric tc Server, and so on.
What is VMware?
VMware: it is a cloud computing software and virtualization. The basis of VMware virtualization technologies is the ESX / ESXi hypervisor in the x86 architecture. A hypervisor is configured on the (physical) server so that several virtual machines can run on the same VMware server virtualization.
All VM can run their operating system. Several virtual machines on the same physical server share some of the shared resources, such as RAM, network, etc.
VMware software is now widely used in virtualized storage and networking, cloud management services, private data centers, office software, and more. VMware professional also started the VMWare ESX server and VMWare GSX server. The VMWare virtualization software is intended primarily for commercial use.
VMware vCenter Server architecture
The three major components of the vCenter Server architecture are:
·         vSphere Web Client.
·         vCenter Server database.
·         vCenter Single Sign-On.
VSphere Web Client: vSphere Web Client is a web application that acts as the user interface. The administrator can manage inventory objects and manage the installation on a vSphere prototype, and virtual machines can access the console. VMware software recently launched the vSphere Web Client based on HTML5 in its latest version (vSphere 6.5).
The vCenter Server database: Server data is stored and managed from resource groups and inventory items. Each instance of vCenter Server has its database.
vCenter Single Sign-On (SSO): SSO is a security token and authentication agent that the user can use to log in once to access the vSphere infrastructure. Further authentication is not required.
Advantages of VMware:
The activated administrator continuously monitors performance. VCenter Server affects the deployment of the virtual machine and blocks unauthorized access. Other benefits include simplifying integration with third-party products, reducing the impact of system errors, and automating workflows.
A server (vCenter) can handle multiple virtual machines alone. The number rises by connecting various occurrences. However, the capability of the server (vCenter) is vast, and this can also be a disadvantage. Therefore, the server database (vCenter) can store all the data. If the number of virtual machines in a given instance is overloaded, the risk of exceeding the database limits is higher: This results in the purchase of vCenter Server (in addition to the existing server).
VMware will not prioritize the Windows (vCenter) server during subsequent vSphere launches. The next version of the vCenter Server has replaced by the server application (vCSA) as a single prototype. Although the Linux version of vCSA has better scalability and configuration, vCSA can only run on virtual hardware and virtual machine clusters. The company can solve the problem by separately creating a group for vCSA. This process requires additional licenses and expensive equipment.
Responsibilities and Job Role
1.       Ability to present ideas in an easy-to-use and business language adapted to executive and executive viewers.
 2.       Ability to successfully manage relationships with other architecture teams, application teams, stakeholders, company representatives, and customers.
 3.       Organizational skills with particular attention to the details of the task, the documentation, and the target dates.
 4.       Solid written, oral, and interpersonal communication skills.
 5.       Team oriented, willing to share knowledge, and collaborate with peers.
6.       Proven strategic and analytical vision with strong problem-solving capabilities.
7.       Able to prioritize and perform tasks in a high-pressure environment. · Ability to investigate servers, storage, virtualization problems, standards, and products.
