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.
