The Java software platform provides a number of features designed for improving the security of Java applications. This includes enforcing runtime constraints through the use of the Java Virtual Machine (JVM), a security manager that sandboxes untrusted code from the rest of the operating system, and a suite of security APIs that Java developers can utilise.
Log4Shell (CVE-2021-44228) is a zero-day vulnerability reported in November 2021 in Log4j, a popular Java logging framework, involving arbitrary code execution. [2] [3] The vulnerability had existed unnoticed since 2013 and was privately disclosed to the Apache Software Foundation, of which Log4j is a project, by Chen Zhaojun of Alibaba Cloud's security team on 24 November 2021.
Secure coding is the practice of developing computer software in such a way that guards against the accidental introduction of security vulnerabilities.Defects, bugs and logic flaws are consistently the primary cause of commonly exploited software vulnerabilities. [1]
The attacker can then combine the oracle with a systematic search of the problem space to complete their attack. [1] The padding oracle attack, and compression oracle attacks such as BREACH, are examples of oracle attacks, as was the practice of "crib-dragging" in the cryptanalysis of the Enigma machine. An oracle need not be 100% accurate ...
As SAST has access to the full source code it is a white-box approach. This can yield more detailed results but can result in many false positives that need to be manually verified. Dynamic application security testing (DAST, often called vulnerability scanners) automatically detects vulnerabilities by crawling and analyzing websites. This ...
Metamorphic testing (MT) is a property-based software testing technique, which can be an effective approach for addressing the test oracle problem and test case generation problem. The test oracle problem is the difficulty of determining the expected outcomes of selected test cases or to determine whether the actual outputs agree with the ...
Management can address security gaps in three ways: Management can decide to cancel the project, allocate the necessary resources to correct the security gaps, or accept the risk based on an informed risk / reward analysis.
The Vulnerability Model (VM) identifies attack patterns, threats, and valuable assets, which can be physical or intangible. It addresses security concerns like confidentiality, integrity, availability, and accountability within business, application, or infrastructure contexts.
