End-point Security

802.1x is an authentication protocol used for network access control. It allows users to be authenticated before being allowed connection to a local area network (LAN). It helps ensure only authorized users can gain access, protecting the network from malicious activity or data loss. To use 802.1x, devices must support the protocol and have an authentication server in place. The device attempting to connect sends credentials which are verified against those stored on the authentication server before granting access.

A web application firewall (WAF) is a security feature designed to protect websites from malicious online activity. It works by inspecting incoming and outgoing traffic for malicious content. If it identifies something suspicious, usually through its own set of rules, the WAF will block the request and alert the site administrator. This helps protect against a wide range of cyber threats such as SQL injection attacks, cross-site scripting (XSS), data breaches, and distributed denial of service (DDoS) attacks. WAFs are essential tools in defending against cyber threats and help ensure websites stay secure for users. With the ever-evolving landscape of cyber threats, investing in a WAF is an important step to ensuring your website’s safety and security.

A DoS attack (Denial of Service attack) is a malicious cyberattack intended to overwhelm a system with requests, making it unavailable for legitimate users. It is used to disrupt services and cause denial of access to resources, like websites or apps. It exploits vulnerabilities in networks or software to flood the system with requests or data packets, using up its resources and making it unresponsive. Companies must be aware and have strategies in place to stop such attacks as they can lead to significant losses in revenue and reputation.

Phishing is a form of social engineering attack used to steal personal information and data. It is typically done by posing as a trusted source and sending malicious links or emails that appear to come from legitimate sources. Attackers usually use phishing techniques to gain access to passwords, credit card numbers, and other sensitive data. Phishing attacks can also be used for financial gain or to spread malware. Cyber security professionals must understand the common types of phishing scams, such as deceptive emails, clone websites, and malicious pop-ups, in order to protect against them. Organizations should also provide awareness training to their employees so they know what to look out for when it comes to phishing attempts. By staying vigilant and taking proactive measures against these threats, companies can reduce the risk of falling victim to a successful phishing attack.

TLS (Transport Layer Security) est un type de cryptage numérique qui permet de protéger les données envoyées sur l'internet. Il crypte les communications entre deux systèmes afin qu'elles ne puissent pas être interceptées par un tiers. Le protocole TLS est couramment utilisé pour les transactions bancaires et le commerce électronique afin de garantir la sécurité des informations des clients, mais il peut être utilisé pour presque tous les types de communication en ligne. Il est également essentiel pour fournir une couche de sécurité supplémentaire contre les cyber-attaques de plus en plus sophistiquées. Le protocole TLS est largement utilisé dans les secteurs de la santé, de l'administration et des services financiers dans le monde entier, et il continue d'évoluer au fur et à mesure que de nouvelles menaces apparaissent. En fournissant des connexions et une authentification sécurisées, TLS est un élément essentiel de toute stratégie globale de cybersécurité.
