Penetration testing (or pen testing) is a security exercise where a cyber-security expert attempts to find and exploit vulnerabilities in a computer system. The purpose of this simulated attack is to identify any weak spots in a system's defenses which attackers could take advantage of.
A penetration test (pen test) is an authorized simulated attack performed on a computer system to evaluate its security. Penetration testers use the same tools, techniques, and processes as attackers to find and demonstrate the business impacts of weaknesses in a system. Penetration tests usually simulate a variety of attacks that could threaten a business. They can examine whether a system is robust enough to withstand attacks from authenticated and unauthenticated positions, as well as a range of system roles. With the right scope, a pen test can dive into any aspect of a system.
Networks. This testing identifies common to critical security vulnerabilities in an external network and systems. Experts employ a checklist that includes test cases for encrypted transport protocols, SSL certificate scoping issues, use of administrative services, and more.
Web apps. Testers examine the effectiveness of security controls and look for hidden vulnerabilities, attack patterns, and any other potential security gaps that can lead to a compromise of a web app.
Cloud. A cloud environment is significantly different than traditional on-premises environments. Typically, security responsibilities are shared between the organization using the environment and the cloud services provider. Because of this, cloud pen testing requires a set of specialized skills and experience to scrutinize the various aspects of the cloud, such as configurations, APIs, various databases, encryption, storage, and security controls.
APIs. Both automated and manual testing techniques are used to cover the OWASP API Security Top 10 list. Some of the security risks and vulnerabilities testers look for include broken object level authorization, user authentication, excessive data exposure, lack of resources / rate limiting, and more.
Mobile devices. Pen testers use both automated and manual analysis to find vulnerabilities in application binaries running on the mobile device and the corresponding server-side functionality. Vulnerabilities in application binaries can include authentication and authorization issues, client-side trust issues, misconfigured security controls, and cross-platform development framework issues. Server-side vulnerabilities can include session management, cryptographic issues, authentication and authorization issues, and other common web service vulnerabilities.
CI/CD pipeline. Modern DevSecOps practices integrate automated and intelligent code scanning tools into the CI/CD pipeline. In addition to static tools that find known vulnerabilities, automated pen testing tools can be integrated into the CI/CD pipeline to mimic what a hacker can do to compromise the security of an application. Automated CI/CD pen testing can discover hidden vulnerabilities and attack patterns that go undetected with static code scanning.
Red Teams are internal or external entities dedicated to testing the effectiveness of a security program by emulating the tools and techniques of likely attackers in the most realistic way possible. The practice is similar, but not identical to,
penetration testing, and involves the pursuit of one or more objectives—usually executed as a campaign.
Blue Teams refer to the internal security team that defends against both real attackers and Red Teams. Blue Teams should be distinguished from standard security teams in most organizations, as most security operations teams do not have a mentality of constant vigilance against attack, which is the mission and perspective of a true Blue Team
purple teams exist to ensure and maximize the effectiveness of the Red and Blue teams. They do this by integrating the defensive tactics and controls from the Blue Team with the threats and vulnerabilities found by the Red Team into a single narrative that maximizes both. Ideally Purple shouldn’t be a team at all, but rather a permanent dynamic between Red and Blue.
Data Box provides a secure solution for data protection by ensuring that only authorized entities can view, modify, or delete your data. This article describes the Azure Data Box security features that help protect each of the Data Box solution components and the data stored on them.
