Description This paper focuses on the significance of secure firmware
Individuals and businesses have undoubtedly reaped numerous undeniable benefits from the advancement and evolution of technology. However, it has come with a significant disadvantage: an increase in cybercrime, cyberattacks, and malware infections, facilitated by the ever-increasing attack surface.The expansion of the network perimeter poses a significant problem, particularly for high-level business operations that need to consistently monitor hundreds of layers of code and security events to guard against intrusions. This task surpasses human capabilities and therefore requires a more efficient solution.
Effective debugging and testing are crucial for ensuring the dependability and performance of hardware in electronics and embedded systems. As a complement to digital simulation in electronic design automation (EDA), JTAG offers on-chip instrumentation standards. It involves a serial communications interface through a dedicated debug port, providing low-overhead access without direct external access to the system address and data buses.
DO-178C is a critical document for software developers involved in the certification of airborne systems and equipment. However, understanding the software life cycle data or artifacts required for certification can be a challenging task. In this blog post, we will explain the minimum software life cycle data required for submission to the certification authority, along with any additional data items that may be requested.
Clipper malware is a type of malware that steals information from a victim’s clipboard, allowing cyber attackers to gain access to their target environments. The malware steals Bitcoin by modifying the victim’s clipboard activity and substituting the destination wallet with the attacker’s. To enhance security, always follow the given ten steps in the blog below.
The blog provides an overview of the taxonomy of DDoS attacks and the primary categories of these attacks, such as volume-based attacks, protocol attacks, and application layer attacks. It also discusses the symptoms and tools used to detect DDoS attacks. Additionally, it covers the emergence of AI-powered DDoS attacks and stresses the importance of implementing measures to prevent and mitigate the effects of DDoS attacks on businesses and organizations.
Once a Trojan is installed on a computer, it allows the attacker to gain remote control of the system, enabling them to carry out malicious activities without the user’s knowledge or consent.
Phishing has emerged as a widespread security threat in the digital age, with scammers employing fraudulent communication tactics to deceive individuals into divulging sensitive information such as passwords, credit card details, and personal data.
QR codes are two-dimensional barcodes that can be scanned by a smartphone or QR code reader app. They are used for various purposes such as product packaging, real estate, and payments. However, they can also make users vulnerable to phishing if fraudulent codes are created. To avoid these risks, users should only scan QR codes from trusted sources, keep software up to date, use reputable antivirus software, and be cautious when entering sensitive information.
Fileless malware operates in a computer’s memory without leaving any trace on the hard drive as a type of malicious software. Fileless malware uses native and legitimate tools already present on a system to carry out an attack, making it difficult to detect. The attackers gain access to the victim’s system first and steal credentials, then creating a backdoor for persistent access. The malware then gathers data and transfers it out of the victim’s environment.
