You're probably familiar with the defense-in-depth or castle and moat approach to cybersecurity. It remains a common model that organizations use to think through their information security. However, as organizations have matured they have sought out new models to enable them to better understand how cyber attackers operate and how best to defend against them.
The Server Message Block Protocol (SMB Protocol) is a client-server communication protocol used for sharing access to files, printers, serial ports, and data on a network. It can also carry transaction protocols for authenticated inter-process communication. In short, the SMB protocol is a way for computers to talk to each other. SMB works through a client-server approach, where a client makes specific requests and the server responds accordingly. This is known as a response-request protocol.
Data is rapidly becoming one of the most valuable assets in the modern world. The digital giants that monopolize data are arguably the most powerful companies in the world, prompting ongoing conversations about anti-trust legislation and digital privacy. Despite the overwhelming value controlled by these entities, as we'll see, even companies such as Facebook are vulnerable to the byproduct of the rapid move to digitization – the data breach epidemic.
The main difference between a security information and event management (SIEM) solution and an intrusion detection system (IDS) is that SIEM tools allow users to take preventive actions against cyberattacks while IDS only detects and reports events. Security information and event management (SIEM) is an approach to cybersecurity combining: Note: the acronym SIEM is pronounced "sim" with a silent e.
A brute force attack is a popular cracking method that involves guessing usernames and passwords to gain unauthorized access to a system or sensitive data. While a relatively simple, brute force methods continue to have a high success rate and account for over 80% of attacks on web applications.
The main difference between intrusion detection systems (IDS) and intrusion prevention systems (IPS) is that IDS are monitoring systems and IPS are control systems. IDS won't alter network traffic while IPS prevents packets from delivering based on the contents of the packet, similar to how a firewall prevents traffic by IP address.
The Health Information Technology for Economic and Clinical Health Act (HITECH Act) was signed into law as part of the American Recovery and Reinvestment Act (ARRA) in 2009. The HITECH Act encourages the meaningful use of electronic health records (EHRs) by healthcare providers and their business associates.
Vulnerability assessment is the process of identifying, classifying, and prioritizing security vulnerabilities in IT infrastructure. A comprehensive vulnerability assessment evaluates whether an IT system is exposed to known vulnerabilities, assigns severity levels to identified vulnerabilities, and recommends remediation or mitigation steps where required.
Vendor risk management (VRM) is a broad category that encompasses all measures that your organization can take to prevent data breaches and ensure business continuity. Legal issues, past performance, and creditworthiness are some of the common VRM issues that all companies review frequently. Additionally, cybersecurity and the reduction of third-party security risks are increasingly important.
Cyber resilience is your ability to prepare for, respond to, and recover from cyberattacks and data breaches while continuing to operate effectively. An organization is cyber resilient when they can defend against cyber threats, have adequate cybersecurity risk management, and can guarantee business continuity during and after cyber incidents.
