SQL injections, cross-site scripting, unauthorized access to resources, remote file inclusion... techniques available to attack applications are as diverse as the infrastructure and services needed to be secured by web application firewalls (WAFs).
Businesses need a WAF that can provide maximum coverage while adjusting to your needs.
Adjust the application climate. Here are seven characteristics to look for when assessing the WAF.
Agility Equals Security Risks
DevOps and agile software methods are great at designing and implementing new applications rapidly and efficiently. Unfortunately, the fluidity of these conditions often poses unintentional safety threats. Ensure that any WAF solution will automatically detect and protect applications connected to the network by automatically developing new policies and procedures.
Cover That Top Ten List
Industry analysts and experts at technology consortiums and communities continue to categorize and recognize the most significant security threats facing organizations in the area of web applications. The WAF solution should include maximum coverage, including all OWASP Top 10 threats.
Bots, crawlers, and spammers using modern strategies to mask malicious traffic can drain resources and scrap sensitive information from websites or cloud-based properties. A successful WAF needs to sniff out these underground cyber assailants. Device fingerprinting detects, blacklists, and blocks the devices used for attacks, regardless of the IP they are hidden behind. Even if the bot dynamically changes its source's IP address, the fingerprint of its computer does not change.
Negative + Positive = Zero-Day Protection
Advanced device and "smokescreen" attacks that use DDoS attacks to obscure other techniques have become commonplace, and zero-day attacks easily exploit newly discovered vulnerabilities. A WAF that uses both negative and positive security models to automatically detect application domains, evaluate possible exposures, and allocate optimal safety policies is essential.
Who’s Knocking at the Door?
Regulation of web access control policies and security protocols is the bread and butter feature of every WAF. How to do that is where the devil is in the details. Ensure that every WAF offering supports user authentication and single sign-on (SSO) features. This refers to two-factor authentication and requires access to site-based applications from outside the enterprise network. Besides, it ensures access to data based on the role/business needs of the customer.
Two Minds Are Better Than One
Cyber attacks are growing in intensity and scope, making it impossible for companies to remain ahead of the rapidly shifting threat environment. The WAF provider can have options for fully managed services for both on-site and cloud-based WAF deployments to assist.
Protection Via Unification
Leading experts believe that the best WAF approach is one that offers both on-site and cloud-based services. It provides a cohesive solution that ensures full availability and protection without security gaps between on-site and web applications and enables fast and simple migration of applications to the cloud.
