Knowing the different terms in cyber security will help you protect your network from threats. Here are some terms to learn: Logic bomb, External network, Threat assessment, and Exploitable channel. Cybersecurity architecture is the overall structure of information security and describes the relationships between components. The key features of cyber security architecture are data security, controls, and preventive mechanisms. In this article, we will go over some of these terms in more detail. Learn more about the cybersecurity glossary of terms.
Logic bomb
A logical bomb is a computer malware infection designed to ‘explode’ when certain conditions are met. In other words, it will execute a program automatically when it detects a specific action or event. Many hackers use this malware to access a targeted system and steal valuable data. However, because it’s not immediately detectable, a logic bomb can be dangerous to the security of a computer network.
It first gained notoriety when a disgruntled UBS employee planted a logical bomb on their network in 2002, deleting critical files from thousands of computers. You hoped the resulting crash would lead to a drop in stock prices. Unfortunately, the logic bomb was discovered only when the programmer tried fixing a programming error. In the case of UBS, the systems administrator was sentenced to several years in jail and paid millions of dollars in restitution.
Exploitable channel
Exploitation is facilitated by the existence of a particular exploitable point, called a hijacking point. These exploitable points are part of an exploitation path, including diverging and crashing paths. In cybersecurity, an exploitable channel can have multiple sub-paths, called stitching points. For example, the first exploitable point in line 14 creates a hijacking point. After this point, there can be many other exploitable points and sub-paths within the exploitable channel.
An exploitable operation must be triggered by memory allocations matching the size of its diverging path. Revery’s exploitable point template records all memory allocations, including symbolic and concrete ones. Revery’s software generates a working exploit at the binary level when an exploitable state occurs. Exploit derivability is a significant challenge to this approach, so Revery explores diverging paths and exploitable points.
External network
An organization’s network connectivity with external organizations is essential to its cybersecurity strategy. These connections might include suppliers, business partners, credit card processors, and market data feed providers. Organizations should carefully consider and manage their external relations, which can significantly affect their information security and compliance posture. In this article, we’ll discuss some of the issues that you should be concerned about. This article will examine some of the organizations’ most common challenges.
The first step in preventing cyber attacks is to secure the external network. Cybercriminals can exploit its vulnerabilities can leverage any security flaws in the network. For example, if a system is accessible via the Internet, cybercriminals may take advantage of the fact that there is no multi-factor authentication on that network. This is especially true for web-facing platforms. Moreover, an external network may also have a higher attack surface than a corporate network.
Threat assessment
Threat assessment in cybersecurity is an integral part of any security program. It involves determining the severity of potential threats and defining countermeasures. You can do threat assessments by observing the behavior of operational personnel. This is known as an active threat assessment, and it can identify potential threats to an organization or its infrastructure. Functional threat assessment involves focused observation of behavior and environment and may include identifying individuals with potentially malicious intent. Threat assessment can also determine the extent of existing controls and potential vulnerabilities.
The first step in risk and vulnerability analysis is threat assessment. Threat assessment involves determining security risks associated with a given location. Threats can include natural disasters, organized terrorist attacks, computer failure, and more. Threat assessments identify the potential for each risk and the likelihood of its occurrence.
Incident handling
Incident handling in cybersecurity is crucial for any organization that relies on cybersecurity to keep its network secure. IT systems gather information and analyze it to determine if a specific event indicates a cybersecurity incident. Security analysts are tasked with looking for multiple factors, such as changed behavior, new types of events, and IP addresses, to determine whether an incident is an actual or potential security risk. Once they have determined the chance, they respond and document their findings.
Next, an incident recovery plan is implemented to recover compromised systems. This includes testing, monitoring, and validating the methods that they compromised. Once the designs are verified as clean, the team will proceed to the next step: cleaning the infected systems and restoring normal operations. Ideally, the entire incident recovery process should take less than 48 hours. During this time, an IT team will be able to identify the cause of the incident and take appropriate action.
