Usually, botnets consisting of a multitude of individual systems are used for the attack. The target of the attack can be servers or other network components. DDoS attacks have become increasingly common in today’s digital landscape, posing significant threats … Read more
The abbreviation WEP means Wired Equivalent Privacy and stands for the oldest standard for encryption and authentication in a WLAN according to IEEE 802.11. It dates back to 1999 and is now considered technically outdated and insecure. What is WEP? Wired Equivalent Privacy, or WEP for short, is a protocol for WLAN encryption that offers … Read more
An exploit reveals security vulnerabilities in software and enables their exploitation. Exploits provide a tool for hackers to penetrate and manipulate computer systems. They can also be used to eliminate vulnerabilities. In the realm of cybersecurity, understanding the concept of an exploit is paramount. Exploits play a significant role in both offensive and defensive strategies, … Read more
To detect and defend against cyberattacks earlier, you need to understand the attackers’ objectives and approach and build defenses accordingly. The Lockheed Martin Cyber Kill Chain is a multi-step model for analyzing attacks and building defenses along with the attack steps. Cyber attacks have become increasingly sophisticated and prevalent. Understanding the methods employed by attackers … Read more
Endpoint Detection and Response is a technology concept and solution to protect and defend against cyber threats from endpoints such as PCs, laptops, tablets, and smartphones or servers. EDR records the behavior of endpoints and analyzes this data. When suspicious behavior is detected, Endpoint Detection and Response provides automated responses to defend against it, such … Read more
Air Gap is a security concept that meets the highest security requirements. It describes the complete physical and logical isolation of computers from each other and from networks. Information exchange between systems is possible, for example, via transportable storage media. Methods such as side-channel attacks exist to overcome an air gap. What is Air Gap? … Read more
Simultaneous Authentication of Equals (SAE) is based on the Dragonfly handshake protocol and enables the secure exchange of keys of password-based authentication methods. In WPA3, SAE replaces the previous methods of negotiating session keys using pre-shared keys and is also used in WLAN mesh implementations. Welcome to the world of Wi-Fi, where we connect to … Read more
A pre-shared key is a key that is used for symmetric encryption methods. In order to encrypt and decrypt data, the pre-shared keys must first be exchanged between the participants involved. Whoever is in possession of the pre-shared key can use the same key to encrypt and decrypt data. Are you tired of your neighbors … Read more
The Point-to-Point Tunneling Protocol (PPTP) can be used to implement virtual private networks over IP-based networks such as the Internet. It is an extension of the Point-to-Point Protocol and is implemented in many operating systems. Due to known vulnerabilities, PPTP is no longer considered secure today. Secure communication plays a vital role in safeguarding our … Read more
Security by Design is a design concept applied in hardware and software development. The security of hardware or software is already considered in the development process and integrated into the complete life cycle of a product. Design criteria include, for example, minimizing the attack surface, using encryption and authentication, and isolating security-relevant areas. Security is … Read more
Common Vulnerabilities and Exposures (CVE) is a standardized list of vulnerabilities and security risks of computer systems. Thanks to the unique naming, the exchange of data about vulnerabilities and security risks is simplified. Sequential numbers uniquely identify the various entries. In the ever-evolving landscape of cybersecurity, vulnerabilities pose a significant threat to the integrity and … Read more
The Common Vulnerability Scoring System (CVSS) is a standard that can be used to uniformly assess the vulnerability of computer systems using a point system from 0 to 10. CVSS is currently available in version 3.1 and recognizes the vulnerability classifications “none”, “low”, “medium”, “high” and “critical”. In cybersecurity, it is crucial to assess the … Read more
