What Is Cryptography?

Cryptography is when the cybersecurity pros use algorithms and other methods to keep sensitive user information (like passwords and social security numbers) safe from anyone who shouldn’t have that information, which is confidential. There are different types of cryptography, like the public keys and hash functions, and each is implemented differently by different people.

What’s the Difference Between Ids and IPS?

IDS stands for intrusion detection system, while IPS stands for intrusion protection system. Both monitor network traffic but they protect your systems differently.

How Do You Secure a Server?

There are at least tons of ways to secure a server, such as:

Using SSL, Private networks and VPNs,  Setting passwords and login expirations,  Firewalls, and Hiding server information.

Cybersecurity Question

What Are the Different Kinds of Data Leaks?

Data leaks can be put into three buckets: Accidental, Intentional, Hacked

What Are Some of the Most Common Cyberattacks?

Following are some of the common cyber attacks that could adversely affect your systems.

Malware, Phishing, Password Attacks, DOS, Man in the Middle, Drive-By Downloads, Malvertising, and Rogue Software.

Explain the XSS Attack and How to Prevent It.

XSS(Cross-Site Scripting) is a cyberattack that enables hackers to inject malicious client-side scripts into web pages. XSS can be used to hijack the sessions, steal cookies, modify DOM, execute the remote codes, crash the server, etc.

You can prevent the XSS attacks by using the following practices:

Validate the user inputs, Sanitize user inputs, Encode the special characters, Use the Anti-XSS services/tools, and Use XSS HTML Filter.

What Is Cognitive Cybersecurity?

Cognitive cybersecurity is the application of AI technologies patterned on human thought processes to detect threats and protect physical and digital systems.

What Is Network Security?

Network security is a subset of cybersecurity that aims to protect data, devices, and systems that are connected to a company’s network.

How Would You Define Threat, Vulnerability, and Risk?

In common layman’s lingo, threat, vulnerability, and risk are different sides of the same coin. However, these three terms have distinct meanings and are used in network security.

What Does AAA Stand for in Network Security?

Authentication is summarized as a process that determines whether the user is genuine or not. They run their different diagnostic tests to find out the authenticity of that user. Accounting refers to a system that helps the company gather information about the activities conducted on the network. Finally, AAA is a framework that helps organizations monitor the network activity, users, and their systems.

How Do You Secure a Server?

There are tons of ways to secure a server, such as the:

Using SSL, Private networks and VPNs, Setting passwords and login expirations, Firewalls, and Hiding server information.

Responsibilities

An information security analyst’s responsibilities include:

  • Maintaining set security standards and practices
  • Monitoring all the information systems for abnormalities and breaches
  • Working with the other security experts to test the safeguards.
  • Keeping the security team up to date on the current security methods and software

What Is an Arp, and How Does It Work?

Address Resolution Protocol is a communicational protocol of the network layer in the OSI models. Its function is to find the MAC address for the given IP addresses of the systems. It converts the IPv4 addresses, which is 32-bit, into a 48-bit MAC address.
How ARP works:
It sends an ARP request that the broadcast frames to the entire network.

  • All nodes on the networks that receive the ARP request.
  • The nodes check whether the request matches with the ARP table to find the target’s MAC address.
  • If it does not match, then the nodes silently discard the packet.
  • If it matches, the target will send an ARP response back to the original sender via unicast.

Skills

The skills required to be an information security analyst include:

  • Extensive knowledge of your information technology and its computer systems
  • Current knowledge of security practices
  • Networking and security fundamentals
  • The ability to respond to incidents quickly as they arise
  • The ability to record and document the incidents

What Is a CSRF Attack? How Is It Executed?

Cross-Site Request Forgery (CSRF) attack, also known as session riding or one-click attack, is a malicious exploit that tricks a victim into performing unintended actions on a website on which they are authenticated.

 It occurs when an attacker exploits the trust between a user’s browser and a targeted website. The attacker takes advantage of the fact that websites often rely on cookies or other authentication credentials to verify a user’s identity.

Steps:

Identify The Target: The attacker selects a target website or web application that has a vulnerability that can be exploited through CSRF.

Craft the Malicious Payload: The attacker creates a malicious payload, typically in the form of HTML or JavaScript code, which will be executed by the victims of the browser.

Create a Malicious Website: The attacker sets up the malicious website or incorporates the malicious payload into legitimate websites that they control. This website will be used to trick the victim into unknowingly performing the actions on the other targeted websites.

Sending Forged Requests: The victim’s browser automatically sends HTTP requests to the targeted website, carrying out actions on behalf of the victim. These requests can include changing account settings that make the purchases or performing any of the actions that the victim’s account is authorized to do.

What Is Arp Poisoning?

Address Resolution Protocol (ARP) poisoning, also known as ARP spoofing or ARP cache poisoning, is a type of cyber attack where an attacker manipulates the ARP tables on a local area network (LAN). 

The attack involves sending falsified ARP messages to associate the attacker’s MAC address with the IP addresses of another device on the network, redirecting network traffic intended for that device to the attacker.

What Is the Difference Between a VPN and a VLAN?

Virtual Private Network

It provides secure remote access to a company’s network resources. It is a network service. The companies wishing to connect with their employees will use the VPN.
