The success rate of finding vulnerabilities in a web app is as low as 1 in 100,000.
Cybersecurity is a constant race between black hat hackers and cyber defenders. Both are frequently trying to identify vulnerabilities in applications. The defenders want to fix the bugs, while the hackers want to exploit them.
Unfortunately, hackers often have the opportunity to exploit vulnerabilities before they are patched. While the manufacturer of the vulnerable software may roll out a patch for an identified vulnerability, organizations still need to apply that patch.
The delays between patch availability and application may leave organizations open to attack, and the sheer number of vulnerabilities in modern software means that the problem is unlikely to be fixed soon. A new solution to application protection is needed, and a good option is runtime application self protection (RASP).
If you are still wondering “What is a rasp used for,” you will get your answer in this article.
While attackers may target all software, web applications are probably the most common target. Web application exposure act as the gateway to sensitive and valuable data.
The web app code is the only thing that stands between an attacker and an organization’s internal databases. So the effects of even a single coding error can be significant. As a result, hackers are willing to put a lot of work into trying to identify that one coding flaw.
In general, the success rates of attacks against web applications can be as low as 1 in 100,000. Hackers need to put in a lot of work to find that big payoff.
However, these attacks can often be easily automated. Simple scripts or commonly available tools can identify common security flaws like cross-site scripting (XSS) and SQL injection. As a result, a hacker can use automation to pick out promising potential targets worth their attention.
Hackers often need to work very hard to find an exploitable vulnerability in a web application. However, most web applications are in fact vulnerable to some attack. In fact, 90% of web applications include a known CVE, which is a publicly known vulnerability. The challenge for hackers is identifying and exploiting this vulnerability before it can be found and patched by the organization’s cyber defenders.
Most organization’s cybersecurity practices are based upon applying patches for known vulnerabilities. It's the ethical hacker, black hat, or internal developer at a company, who identify the vulnerability in the company’s software. When the company becomes aware of the vulnerability (either through a bug report or its active exploitation), they issue a patch to close the vulnerability, a process that usually takes 90 days or less. Once that patch is available, individuals and organizations apply the patch to their systems, making it no longer exploitable by attackers.
The vulnerability that is usable to hacker is the gap between its initial discovery and the application of a patch by an organization. Unfortunately, this window can often be reasonably wide. If the vulnerability is ethically reported, the details of the bug aren’t made public until a patch is made available, so the delay is the time that it takes the organization to apply the patch. However, this delay is 38 days on average and can be much longer.
On the other hand, the average time between the public announcement of a vulnerability and an exploit being available on the Internet has dropped to about 14 days. This gives an attacker the better part of a month to scan for and exploit machines using a vulnerability whose patch is publicly available and just waiting to be applied. And this only counts the time after the exploit is publicly available, not when its developer might be privately using it themselves.
The traditional method of application protection through patching isn’t that effective and the sheer number of vulnerabilities that an organization needs to patch is overwhelming and growing constantly. It was demonstrated very clearly by the WannaCry outbreak, which took advantage of a vulnerability whose patch was available months before the ransomware worm was released.
Security solutions like web application firewalls (WAFs) do a lot to help fix the problems with slow patch cycles. Typically, WAF developers are faster to release signatures for exploits, allowing them to identify and block potential attacks before they can reach vulnerable systems. However, even WAFs often need a signature to be available to identify and prevent a new attack accurately.
A new paradigm is needed for vulnerability management, and runtime application self-protection is a promising solution. Leading WAFs use anomaly detection to identify unusual traffic that may be intended to exploit an unknown vulnerability. However, WAFs are often used to protect the organization’s entire web presence, which limits the insight that they can achieve into any particular application.
RASP, on the other hand, provides personalized web application protection. A RASP solution wraps around an application, monitor its inputs, outputs, and behaviors for any anomalies. This tight integration provides the RASP system with the insight necessary to identify even novel attacks based on their impact on the application’s behavior.
The RASP application security has the ability to protect against even zero-day attacks makes it a promising solution to the problem of vulnerability management. While fixing bugs in applications is probably still desirable in the long term, RASP can remove the urgency that organizations face regarding patch management and ensures that slow patch cycles do not leave an organization vulnerable to attack.
Runtime security can bre defined as the process of securing the on-going operations through self-analysis of the system. To put it simply, software monitors the inputs, and block those that could allow attacks. The following are some of the threats against which, tunrime security is deployed:
RASP is a security technology that is used for protecting against threats that occur during runtime. RASP works differently from that of firewalls and take the following measures to thrwat the cyber attack:
