What Does A Cybersecurity Analyst Do

Cybersecurity analysts strive to preserve the integrity of sensitive data by defending infrastructure and systems from cyberattacks. To protect these assets, cybersecurity analysts evaluate system vulnerabilities through diagnostic testing and traffic monitoring. Based on the results of these assessments, cybersecurity analysts design and implement risk management strategies. Cybersecurity analysts also respond to cyber attacks, conduct forensic analysis of previous cyber incidents, and work to ensure organizational compliance with relevant security standards and protocols.

Explain Social Engineering And Its Attacks

Social engineering is the term used to convince people to reveal confidential information.

There are mainly three types of social engineering attacks: 1) Human-based, 2) Mobile-based, and 3) Computer-based.

• Human-based attack: They may pretend like a genuine user who requests higher authority to reveal private and confidential information of the organization.
• Computer-based attack: In this attack, attackers send fake emails to harm the computer. They ask people to forward such email.
• Mobile-based attack: Attacker may send SMS to others and collect important information. If any user downloads a malicious app, then it can be misused to access authentication information.

Q: Define The Salting Process And What Its Used For

A: Salting is the process wherein you add special characters to a password in order to make it stronger. This increases password strength in two ways: it makes it longer and it adds another set of characters that a hacker would have to guess from. Its a good measure to take for users who tend to habitually make weak passwords, but overall its a low-level defense since many experienced hackers are already familiar with the process and take it into account.

Explain A Brute Force Attack Along With The Steps To Prevent It

Brute force attacks strive to unlock password-protected assets by repetitively entering authentication credentials either manually or via automated credential stuffing . To prevent brute force attacks, cyber security professionals should:

• Make unique login URLs for various user groups.
• Monitor server logs and analyzes log files.
• Use two-Factor Authentication.
• Limit logins to a particular IP address or range.
• Implement CAPTCHA as part of the login process to prevent automated attacks.
• Throttle login attempts .
• Make the root user inaccessible via SSH.

In Our Computing Labs Print Billing Is Often Tied To The Users Login Sometimes People Call To Complain About Bills For Printing They Never Did Only To Find Out That The Bills Are Indeed Correct

What do you infer from this situation? Justify.

Sometimes they realize they loaned their account to a friend who couldnt remember his/her password, and the friend did the printing. Thus the charges. Its also possible that somebody came in behind them and used their account

This is an issue with shared or public computers in general. If you dont log out of the computer properly when you leave, someone else can come in behind you and retrieve what you were doing, use your accounts, etc. Always log out of all accounts, quit programs, and close browser windows before you walk away.

What Is Host Intrusion Detection System

The Host-based intrusion detection systems are applications that operate on information collected from individual computer systems and serves on the existing system and compare with the previous mirror/snapshot of the system and validates for whether any data modification or manipulation has been done and generates an alert based on the output.

It can also figure out which processes and users are involved in malicious activities.

How Can One Set Up Application Security

First, we have to implement a secure SDLC framework for our project, i.e., software development. Then, I should know about the open web application security project and enhance my skills in the updated threats. Then, notice the security requirements for the application from the beginning stage of the development and maintenance industry application security practices as much as quickly.

After that, one should implement secure application design and architecture. The next step is implementing best and safe coding practices, including input validation, authorization, and authentication. Finally, ensure well-rounded security of the application for the coding cycle to implant a culture of secure coding cryptography, session management, and error handling at the stage of the secure SDLC.

And still think that the vulnerabilities exist, rate them and publish comprehensive reports about associated risks and alleviations of the exposures. After everything completes, its essential to scan the entire application using tools like AppScan, Fortify, etc., to conduct various tests such as Static Application Security Testing, Dynamic Application Security Testing, Angle sign-on, and Encryption. Then the software code review process will be undertaken and ensures that the most emitted phase, Post-deployment, and maintenance is secure at all levels.

So, implementing Application security for web applications is essential as the functionality and design of the applications.

What Exactly Do You Mean By Security Testing

One of the most important kinds of software testing is security testing. Before an app is made available to the public, it must be completed. This kind of testing finds weaknesses in software, including network- or web-based applications. As a result, it defends against assaults and intrusions. Any sensitive data in an app is secured from leaking thanks to security testing. It is also important to note that an organization or developer must perform it frequently to find and address various vulnerabilities, similar to any other form of software testing.
