When you hear about offensive work in security, it may conjure up images of malware, malicious actors, and mischief. But offensive security is also an important component in protecting your digital assets by proactively putting your security controls to the test. In a world of rapidly evolving landscapes and threats, offensive security provides a practical way to test new concepts and ideas in a safe setting, gathering data on vulnerabilities and weaknesses that can improve your defenses and demonstrate your security posture.
In simple terms, offensive security involves testing an organization’s defenses by conducting simulated attacks to identify any weaknesses that can be exploited in information security protocols. The goal of a security engineer or offensive security certified professional is to discover vulnerabilities before malicious actors can exploit them, and to make necessary adjustments to improve security. Offensive security professionals use a proactive approach to cybersecurity that complements defensive measures like firewalls, antivirus software, and intrusion detection systems.
Defensive security is a reactive approach that focuses on securing an organization against potential threats. It often relies on securing the perimeter and applying established best practice in tactical areas of security awareness or security weaknesses like security hygiene, data handling, or access controls, as well as strategic considerations such as defense in depth or zero trust.
Offensive security is a proactive approach that turns theory into practice. It means looking at security as a problem to be solved, rather than an abstraction. The goal of offensive security is to actively identify and fix vulnerabilities of advanced web attacks before they can be exploited, often by applying creativity to an organization’s specific assets, practices, and subjective posture.
Both approaches are essential for a comprehensive cybersecurity strategy. However, the main difference is that defensive security is focused on preventing attacks, while offensive security is focused on finding and fixing vulnerabilities or security issues that could range from network security to wireless attacks.
There are a number of approaches to offensive security service: one common theme is that while they are supported by automation, human hackers play a crucial role.
Traditional cloud security or cyber security focuses on best practice and builds defenses based on presumptions and expectations of how malicious actors would behave. Investing in offensive security is an opportunity to put these theories to the test and see how defensive measures hold up against active tests. It’s a way of stress testing any assumptions baked into your security, and potentially finding blind spots or gaps.
Offensive security covers the application of tried and tested methodologies, particularly in pen testing, as well as tapping into the latest innovations from emerging technologies and associated techniques. Bringing this range of knowledge to bear amounts to a comprehensive test of your security that can provide clear recommendations on handling vulnerabilities, as well as a confident assessment of your security posture.
Certain industries, such as financial services and defense, have high standards of regulation, which includes security. Companies operating in these sectors often need to demonstrate the use of offensive security such as pen tests to meet these requirements and assure regulators that security standards are being met, avoiding associated penalties.
Security can be hard to define and benchmark, with Knightian uncertainty common and some risks difficult to quantify. Offensive security can offer quick feedback through testing, as well as providing clear ROI from spending on “pay for results” investments such as bug bounty programs.
Some great minds have considered how to define security: it is a process rather than a destination, an emergent property rather than a characteristic. But we also believe that high quality security means engaging with the security community, which includes these thinkers as well as the hackers, testers, developers, and more. Investing in offensive security is a way to engage directly with some members of this community, but also a way to build a brand for taking security seriously. Like any brand this helps your relationship with stakeholders, including regulators, employees, prospective hires, and customers.
Offensive security frameworks are methodologies that security professionals use to understand the tactics, techniques, and procedures (TTP) of cyber adversaries. These frameworks provide a structured approach to identify vulnerabilities, simulate real-world attacks, and develop strategies to mitigate potential threats. All frameworks provide valuable insights into attacker behavior, and they should be used together for the most comprehensive understanding of offensive security.
Three of the most widely recognized offensive security frameworks are the MITRE ATT&CK, Lockheed Martin Cyber Kill Chain, and the Mandiant Attack Lifecycle.
There are too many tools to cover in one post, but the below list includes some of the trusty hacker aids that are commonly used. It’s worth noting that many are open source, and ingenuity is more important to hackers than proprietary investments.
It is hard to know how good a new car is until you have taken it for a ride. Offensive security is the practical, hands-on approach to ensuring that the steps you are taking to protect your organization are paying off, and to finding any gaps or oversights across your estate. It tests your assets, your tools, your processes, and even your people. While it is necessary for compliance in some sectors, the main benefit is the practical benefits of knowing how your defenses stack up against attackers.
Investing in offensive security is a way of getting skin in the game and having an accurate assessment of security posture. The best way to start is by investing in crowdsourced security testing: this allows you to access offensive security while only paying for results.
