Top 20 Information Security Analyst Interview Questions and Answers for 2022
What Do You Mean by Cybersecurity?
Cybersecurity is the protection of critical systems and sensitive information from digital security threats. The field of cybersecurity encompasses infrastructure security, network security, cloud security, and application security. Cybersecurity protocols are responsible for preventing security breaches that could compromise an organization’s data and infrastructure. Cybersecurity encompasses security engineering and architecture, incident response, consulting, testing, and ethical hacking.
7. What is the difference between VA(Vulnerability Assessment) and PT(Penetration Testing)?
Vulnerability Assessment is the process of finding flaws on the target. Here, the organization knows that their system/network has flaws or weaknesses and want to find these flaws and prioritize the flaws for fixing.
Penetration Testing is the process of finding vulnerabilities on the target. In this case, the organization would have set up all the security measures they could think of and would want to test if there is any other way that their system/network can be hacked.
24. How often should you perform Patch management?
Patch management should be done as soon as it is released. For windows, once the patch is released it should be applied to all machines, not later than one month. Same goes for network devices, patch it as soon as it is released. Proper patch management should be followed.
3. What is the difference between data protection in transit and data protection at rest?
Data protection at rest means protecting data that is in storage. Attackers can gain access to this data if they gain access to the storage device it is on, either physically or digitally.
Data protection in transit means securing data that is sent over the network, such as to and from the internet.
Both of these types of data can be protected with security tools such as firewalls and network access control. As well, both types of data should be encrypted. That way, an attacker gains access, they cannot read the data without cracking the encryption.
What Do You Mean by Port Scanning?
Ports are vital assets that are vulnerable to security breaches. Attackers use port scanning to locate open ports that are sending or receiving data on a network. This technique is also used to assess a host’s vulnerabilities by sending packets to various ports and analyzing their responses. Nevertheless, port scanning is not an inherently malicious activity—cybersecurity specialists use port scanning to evaluate network security.
Developed in the 1970s, the OSI (Open Systems Communications) model is a conceptual framework that illustrates the architecture and communication functions of a network system. The model, which consists of seven collaborative layers, characterizes these functions into rules and describes how layers operate collaboratively to transmit data.
39. Explain Phishing and how to prevent it?
Phishing is a Cyberattack in which a hacker disguises as a trustworthy person or business and attempt to steal sensitive financial or personal information through fraudulent email or instant message.
You can prevent Phishing attacks by using the following practices:
