What is Computer Security Kinds of Attacks in Computer Security Article

Every day, technology is developing and changing our modern world as it expands. Online use is growing tremendously, leaving us more sensitive to cyber threats accordingly. So what is computer security? Thanks to computer security you can lower the impact of privacy violations and the damage they cause by studying how cybercriminals strike or how to protect the networks and data against these threats. Computer security aims at protecting systems against damage, fraud, and illegal usage of computer systems and records. The key reason why users are always targeted is that there are inadequate protections to deter invaders, and cybercriminals leverage these vulnerabilities quickly. Computer safety methods guarantee that the machines and their file systems are secure, complete, and accessible. The topics that you can find below will be explained in this computer security article:

  1. The reasons of users being attacked
  2. Types of attacks
  3. How to secure?

The Reasons of Users Being Attacked

Understanding what is computer security will give you answers in this computer security article with the explanations found below;

1. Disturbing the Stability of a Company

When a company is interrupted, the company’s earnings, theft, and credibility are greatly damaged.

2. Stealing of Knowledge and Disclosure of Data

Attackers capture confidential that organizations snatch and sell them on the dark web to people or entities.

3. Cause Confusion and Panic by the Destruction of Vital Infrastructure

Cyber-terrorists target a business causing harm to a region.

4. Loss of Income for the Destination

Attackers strike and destroy their systems to quite an extent that they are required to spend large amounts of money to fix the problem.

5. Attaining the Strategic Goals of a State

Global powers hold a watch on one another continually and even use cybercriminals to rob military confidences.

6. Claiming Restitution

Attackers use rankings to restrict web pages or databases and then unlock access when a rescue is compensated.

7. Damage Goal Credibility

An attacker may have selfish motivations to threaten a company or employee for the sake of suffering its popularity.

8. To Encourage Spiritual and Social Belief

Attackers may manipulate religious faith or a particular political ideology on platforms that normally persuade people to vote up in a particular way.

Kinds of Attacks in Computer Security

1. Denial of Service (DDoS)

This is an intrusion utilized to remove links to machine services by inserting malicious traffic into the database. In order to jamb the resources desperately, the Botmaster orders all robots to enter a service simultaneously. Then a legal person could do so if he wishes to use the same service.

2. Malware Attack

The software disrupts or destroys a machine, and is malicious. Four key malware forms are as follows;

  • Keylogger
  • Virus
  • Worms
  • Trojan horse

3. Man in the Middle

Say, you want to make an online sale, for instance. You connect and make the transfer with your card. You must enter the specifics of your card and the PIN during a transaction. You are spooled and monitored by the cyber intruder. You can have links to all this data once you log in your data. That’s why you should understand what is computer security so that you can take the necessary actions.

4. Phishing

Bait is sent by the intruder, often as an email. It allows people to communicate their information. If anyone is an X bank client, the connection will be opened and the information entered. Yet those e-mails still dovetail. Banks don’t deliver those letters.

5. Eavesdropping

Hackers monitor the platform’s traffic and the job it does. Below, you can see three ways that the intruder will supervise you:

  • Through Email
  • Websites you visit
  • Items you download

6. SQL Injection

As the title indicates, a hacker injects harmful information into a SQL statement with a Security vulnerability. Only on Web pages does this form of attack occur. Facebook is the perfect example. On the Facebook page is a database. The attackers enter this account and log in to use the login details of others.

7. Password attack

Another reason to understand deeply what is computer security is described in this section. Attackers use the following methods to break a username or to discover a password:

  • Dictionary Attack: In this form, any IP address available through the database is handled
  • Brute Force: This is the process of testing and failure used for login or data decoding. It requires a long time for this assault.
  • Keylogger: Keylogger logs all hits on the button, as the title mentions. Many users use it to retrieve passwords and contact knowledge
  • Shoulder Hopping: Hackers peer and see the user’s claw.
  • Rainbow Table: Rainbow tables containing pre-computed data blocks. Hackers are using this table to search the passwords for the user.

There are different kinds of passwords tools to chose from in order to protect yourself from different attacks. Check some options here!

8. Social Engineering

To comprehend what is computer security you need to understand the term social engineering. Hackers are creating social conditions that facilitate login sharing. Let’s assume, for instance, that you’re out and you’re calling. The guy said he is from the IT team and finds that your machine is affected. He asks for the code to be exchanged. You could trust him and share your username. But the operator was probably an attacker and how he got the secret. You can risk the business resources now that you have access to it. Learning the procedure of the company on login exchange is the only way to prevent the consequences of social engineering.

How to Ensure Computer Security?

1. Two-way Authentication

Double-factor authentication provides a security barrier to authentication by finding it difficult for outsiders to enter computers or the internet activity of individuals. You must check the CVV number of your account when making online transactions, so you get another verification with your contact phone.

2. Using Secure Passwords

You have to make strong passwords. So in this way, it will be difficult to hack you. The most efficient kind of password in this sense should contain the following;

  • At least 15 characters.
  • Capital letters.
  • Special characters.
  • Numbers.

3. Routine Updates

Keep applications and your device always up to date. Most patches include more cyber threat protections.

4. Using Antivirus Programs

Antivirus is an antivirus software program for malware protection, identification, and elimination. For instance, Norton, Quickheal, and McAfee are antivirus examples.

5. Firewalls

Firewalls prohibit unauthorized web users, particularly intranets, from reaching private internet-connected sites.

6. Anti-Phishing Tactics

In the case you receive an email that looks doubtful to you, it is recommended in this computer security article to make the followings happen:

  • Do not use the email connection.
  • Do not offer any sensitive information as requested.
  • Do not access files that have been added to the email.

7. Encryption

So here, you should have understood what is computer security. This last method, which is encryption, is a method by which similar pace text is converted into indecipherable and conversely. Encryption is utilized in a variety of actions such as

  • Online payment through banks
  • Passwords for the machine
  • Purchases in e-commerce

Bottom Line

In this article, we discussed why computer security matters. The number of cyber threats is increasing every day. Therefore, you need to have a piece of knowledge on cybersecurity concepts to protect yourself and your business against attacks.
