    Strengthening Your WAF Through Manual Penetration Testing


    Strengthening Your WAF

    A penetration take a look at, additionally generally known as a pen take a look at or a vulnerability evaluation, is the time period given to a simulated cyber-attack on a pc system that’s supposed to check out potential vulnerabilities that could possibly be exploited by hackers.

    Penetration testing is usually used for the aim of augmenting net utility firewalls relating to net utility safety and web site safety.

    Penetration testing usually includes making an attempt to breach a wide range of completely different utility techniques resembling frontend or backend servers and utility protocol interfaces to search out such vulnerabilities, together with the likes of unsanitized inputs which could possibly be susceptible to code injection assaults.

    WAF safety insurance policies can then be finetuned by the insights that the penetration take a look at is ready to present, as can patch points discovered throughout vulnerability testing. 

    The Completely different Phases of Penetration Testing  

    There are usually 5 completely different levels to a penetration take a look at:

    1. Planning and inspection
    2. Scanning
    3. Gaining entry
    4. Sustaining entry
    5. Evaluation

    Planning and inspection

    The primary stage includes the scope and total intention of a penetration take a look at being outlined, together with the techniques that the take a look at will tackle and the strategies of testing that shall be utilized.

    This stage additionally includes the gathering of intelligence resembling mail server and area and community names to achieve a larger understanding of the workings of a community and the potential vulnerabilities it might comprise.


    The second stage is to work out the methods wherein the goal utility will react to varied makes an attempt on the intrusion, which is usually performed by way of

    • Static evaluation
    • Dynamic evaluation

    Static evaluation inspects the code of an utility with a view to estimate its precise operational habits, and these instruments can even have the code scanned in its entirety in only one cross.

    Dynamic evaluation inspects the code of an utility whereas it’s operating. It is a way more sensible scanning technique because it gives a real-time have a look at the efficiency of an utility.

    Gaining Entry

    The third stage makes use of net utility and automatic assaults like backdoors, cross-site scripting, and SQL injection to find the vulnerabilities of a goal, which the testers will then try to use often by escalating privileges, intercepting site visitors, stealing information, and so forth in a bid to find out simply how a lot harm such assaults may truly trigger.

    Sustaining Entry

    The fourth stage determines whether or not or not the vulnerability may be exploited to achieve a persistent presence inside the focused system to permit in-depth entry to a foul actor.

    The general concept is to attain an correct imitation of threats which can be superior and chronic that may stay in a system for months at a time with a view to steal probably the most delicate information in a company. 


    A report is then compiled of all the info collected from the penetration take a look at that features the vulnerabilities in web site safety that the safety testing exploited, the size of time that the penetration tester was capable of stay undiscovered within the system and the delicate information the take a look at was capable of entry.

    Safety personnel can then analyze this report to assist reconfigure the WAF settings of an enterprise and different utility safety options with a view to patch up any vulnerabilities that the take a look at found and forestall future assaults.

    Penetration Testing Methodology

    1.    Exterior Testing

    Exterior penetration exams are focused at firm property that may be seen by way of the web resembling an online utility, firm web site, and area identify, and e mail servers. The intention of those exams is to get entry after which extract essential information.

    2.    Inner Testing

    Inner exams see testers which have entry to functions behind their net utility firewall simulating what would occur if an assault was launched by a malicious insider. Malicious insiders don’t have to be rogue workers however an worker which will have had their credentials stolen due to a phishing assault.

    3.    Blind Testing

    Blind exams see a tester given the focused enterprise’s identify and nothing extra, offering safety personnel with a real-time examination of how actual utility assaults truly happen.


    Whereas a Internet Software Firewall is crucial to guard your net functions from malicious requests, it isn’t the last word safety answer. A WAF is meant for use together with safety testing/penetration testing. Guide penetration testing can unearth complicated safety flaws and chain assaults that an automatic take a look at won’t have the ability to choose up.
