This phase also to some extent would check the response of the IT staff on the receiving end of an attack (Which could be done by launching a limited DDoS attack). Reconnaissance phase – Verifying parameters like available IP’s, API’s, mitigation systems in place, various “L7 challenges” and “behavioral algorithms” within the mitigation technology.This type of testing is more geared towards organizations with mitigation systems installed. More advanced DDoS testing can involve a prolonged APT (Advanced Persistent Threat) simulation, similar to groups like “anonymous” or other cybercriminals would do trying to attack an organization. If you’ve never performed any DDoS testing on your infrastructure, you’ll likely be surprised (disturbed) with results at this initial phase of testing. This is done by launching varying Mbps (Megabits Per second), PPS (Packets Per second) or CPS (Connections per second) of different L4 and L7 attacks against a system, by doing this the reliability of “service continuity” is evaluated under a particular or combined DDoS attack. Most systems without any DDoS mitigation infrastructure or service in place will likely have “downtime”. Layer 7 attacks are normally a lesser rate of traffic, targeting the attack towards the application layer.Ī DDoS test can mean launching L4 and/or L7 attacks against known IP’s and services. Layer 4 attacks are normally a high rate of traffic, attacking the network layer. This can be either a simulation of well-known “ layer 4” (L4) volumetric or “ layer 7” (L7) application attacks. “ DDoS Testing” (Distributed Denial of Service Testing) is a legal way of inspecting your network’s susceptibility to DDoS attacks and how easy it is to affect service availability. Such decisions, for whatever the reasons, are not uncommon and often thought of as a reasonable way forward in terms of business logic, the approach is debatable. They’d now also rely on that WAF for security if that’s the decision! Try convincing a backend web developer, and his manager, all DB (Database) access functions need to be reprogrammed in a project that’s been around for 7 years they may decide, a WAF (Web Application Firewall) in front of the web daemon is the best option at that point □ Dependent on organization structure and size this can be a lengthy process stretching out weeks or months. The fact is that some security flaws may require multiple teams, as well as vendors to work together to solve a single bug. How and when security bugs are addressed is normally a practicality issue. Of course this can be a complex and timely process in reality.Įach security bug will normally be addressed with what is deemed to be the easiest bug to exploit, coupled with the highest amount of damage the exploitation of that bug could cause. Perhaps the most important phase of a pentest, is that once weaknesses are identified those weaknesses will be closed to make it tougher for a potential attacker to exploit an organization. What happens once vulnerabilities are found during a pentest? It’s important to note, by law some companies are required to have frequent pentests if they require various compliances such as PCI, HIPAA or GLBA. A pentest can be anything from a few days to a few months in length, depending on the organization being tested and the level of risk that organization wishes to mitigate and understand. the internet or from the internal network itself and of course both internal and external tests could also be tested simultaneously. Some common aspects validated are:Ī pentest can be performed either from the external perimeter i.e. There are many types of pentests but generally they “ validate” security mitigation systems and setups. The logic is that if a pentester can gain access to your system and extract data or cause other damage, so can a criminal who has some agenda against your organization. Pentests are performed in order to strengthen your organizations cyber security posture. These factors will normally determine whether or not pentesters will be successful in gaining full access to the system. The results are dependent on the type of pentest ordered and the skill of the pentesters at work. This is done in order to validate if the vulnerability found, is in fact exploitable. This comprises of an intense and legal security assessment, done on a network by a security professional (Certified or not) to actively find vulnerabilities that could potentially be exploited to gain access to your system.Ī “ pentester” in some cases will try to exploit vulnerabilities found. Penetration Testing is commonly referred to as “pentesting”.
