A WAF or web application firewall helps protect web applications by filtering and monitoring HTTP traffic between a web application and the Internet. It typically protects web applications from attacks such as cross-site forgery, cross-site-scripting (XSS), file inclusion, and SQL injection, among others. It is a protocol layer 7 defense (in the OSI model), and is not designed to defend against all types of attacks. This method of attack mitigation is usually part of a suite of tools which together create a holistic defense against a range of attack vectors. It operates through a set of rules often called policies. These policies aim to protect against vulnerabilities in the application by filtering out malicious traffic. #cybersecurity #socanalyst #blueteam #webattack

🌐 Day 19 of #100DaysOfCybersecurity 🛡️ Today’s Focus: Web Application Firewalls (WAFs) 🔥 Key Insights from Today’s Deep Dive into WAFs: 🔑 What is a WAF? A Web Application Firewall monitors, filters, and blocks HTTP traffic to and from web applications. 🛡️ Types of Protection: WAFs protect against threats like SQL Injection, XSS, and DDoS attacks, helping secure web apps from common vulnerabilities. 🔐 How WAFs Work: By analyzing requests, they can block malicious input or traffic patterns that don't match expected behaviors. 💡 Evasion Techniques: Attackers try to bypass WAFs using encoding, obfuscation, and crafted payloads, which makes understanding both sides crucial for security. #Cybersecurity #WebSecurity #WAF #AppSec #SQLInjection #XSS #BugBounty #EthicalHacking #100DaysOfCybersecurity

Main keys to remember when dealing with IDOR is to use server side access controls, indirect references, and conduct security test often. A lot of these SAAS apps have misconfigured rights control which can allow someone access by just modifying the url. Stay woke guys.

Learn how to fortify your defenses against cyber threats with web application firewalls (WAFs) – a crucial shield against common web application attacks. Started in the late 1990s, WAFs have become indispensable in safeguarding online assets, but failing to utilize them leaves your applications vulnerable to malicious exploits like SQL injection, cross-site scripting (XSS), and more. Here are three essential tips to effectively implement WAFs: 🔹 Implement a robust WAF solution tailored to your application's needs. 🔹 Regularly update WAF rules to adapt to evolving threats and attack techniques. 🔹 Monitor WAF logs diligently to swiftly identify and respond to potential security incidents. Let's chat about how TeamLogic IT can safeguard your digital assets and propel your business forward!

🚨 Cross-Site Scripting (XSS): A Persistent Threat to Web Security! 🚨 XSS vulnerabilities remain a serious concern, allowing attackers to inject malicious scripts into trusted websites and exploit users’ browsers. These attacks can lead to session hijacking, data theft, and even malware distribution. 💡 There are three main types of XSS attacks: • Stored XSS: Where the malicious script is permanently stored on a server. • Reflected XSS: Where the script is reflected off a server and executed on a user’s browser. • DOM-Based XSS: Occurs on the client side, manipulating the website’s DOM. To safeguard your applications, it’s essential to validate inputs, escape output properly, and enforce strong Content Security Policies (CSP). Learn more about XSS, how does it occur, and what’s the impact to your business at Riskopedia https://lnkd.in/gm9VRWMu #Cybersecurity #WebSecurity #XSS #AppSec #WebDevelopment
