Unless your system is truly stress tested there’s no way for you to determine if the security measures in place are adequate.
You can develop the best policies, scan the network every week, and patch systems daily, but you will never be 100% vulnerability free. This is referred to as the “trial and error” approach, however, there is a high degree of technical skill involved in this process.
One of the easiest ways threat actors break into a system or network is by deploying a series of exploits known to work, such as Kerberoasting.
If successful, the malicious payload is delivered and you can consider yourself breached. In short, threat actors attempt to retrieve sensitive information by manipulating people into clicking links, downloading attachments, or providing access over the phone. In fact, 92% of malware is delivered by email.
Malware is often deployed through phishing, vishing, or smishing, which are all types of social engineering attacks. There are a number of methods threat actors utilize to deploy malware into a network or system including social engineering and exploiting vulnerabilities. How Does Malware Infect A Computer Or Network?

Systems infected with malware will present with symptoms such as running slower, sending emails without user action, randomly rebooting, or starting unknown processes. Malware, or malicious software, is any piece of software that was written with the intent of doing harm to data, devices or to people. How Does Malware Infect A Computer Or Network?.It’s important to note that no system is 100% vulnerability free or “hacker-proof.” If a threat actor has enough time, resources, and manpower to launch an attack then chances are they will find a way in. You can mitigate or prevent malware attacks by developing security policies, implementing security awareness training, using app-based multi-factor authentication, installing anti-malware & spam filters, changing default operating system policies, performing routine vulnerability assessments. Threats, vulnerabilities, and attacks are examined and mapped in the context of system security engineering methodologies.The most common types of malware include viruses, keyloggers, worms, trojans, ransomware / crypto-malware, logic bombs, bots/botnets, adware & spyware, and rootkits. The course also includes an introduction to basic cyber security risk analysis, with an overview of how threat-asset matrices can be used to prioritize risk decisions. Network attacks such as distributed denial of service (DDOS) and botnet- attacks are also described and illustrated using real examples from the past couple of decades.įamiliar analytic models are outlined such as the confidentiality/integrity/availability (CIA) security threat framework, and examples are used to illustrate how these different types of threats can degrade real assets. Examples include simple Unix kernel hacks, Internet worms, and Trojan horses in software utilities. An overview of how basic cyber attacks are constructed and applied to real systems is also included. This course provides learners with a baseline understanding of common cyber security threats, vulnerabilities, and risks.
