What is cyber security?

Cyber security is the activity of securing systems, servers, portable devices, electrical components, networks, and data from malicious cyberattacks.

Individuals and businesses utilize this method to prevent illegal access to data centers and other digital systems.

Define Cyber Attack

A cyberattack occurs when there is an intentional and destructive attempt to breach an individual’s or organization’s information system.

While most assaults have an economic aim, certain recent operations have shown data destruction as a goal. Malicious actors frequently seek ransom or other forms of economic gain. However, assaults can be carried out for a variety of reasons.

Leading 10 types of cyber security attacks

  • Malware
  • Phishing
  • SQL Injection
  • Man-in-the-middle attack (MITM)
  • Denial of Service (DOS)
  • Zero-day exploit
  • Cryptojacking
  • Password attack
  • Cross-site Scripting
  • Insider Threat

Malware

It encompasses a broad spectrum of dangers, such as spyware, viruses, and worms. Malware exploits a network weakness when a button is pressed on a “seeded” harmful link or email attachment, which is exploited to install malicious software on the system.

They can also penetrate a network by exploiting a vulnerability. An infected pen drive can be used.

Prevention:

Make use of antivirus software. It can protect your machine against malware. Avast Antivirus and McAfee Antivirus are two famous antivirus programs.

Make use of firewalls. A firewall filters the traffic entering your device.

Phishing

These attacks are quite common and entail sending large numbers of fake emails to unsuspecting individuals while masquerading as coming from a trustworthy source.

Phishing attacks can also occur through social networks, other online groups, and direct messaging from other users with concealed agendas.

Social engineering and other public information sources are routinely used by phishers to obtain information about their work, interests, and activities. These attacks can also occur via phone calls (voice phishing) and text messages (SMS phishing).

Spear phishing refers to focused attacks on specific companies or individuals.

Whaling attacks on top executives and key stakeholders within a company.

Pharming using DNS cache poisoning to acquire user credentials via a false login landing page.

Prevention:

Utilize an anti-phishing toolbar.

Keep your passwords up to date.

SQL Injection

The server is forced to deliver protected data when an attacker uploads malicious code into a database using a server query language (SQL).

Typically, this attack involves inserting malicious code into an unprotected website comment or search box. SQL injections can be avoided by using secure coding techniques such as regular expressions with parameterized queries.

Prevention:

Use a system for intrusion detection that is designed to identify unwanted network access.

Validate the information provided by the user. 

Man-in-the-middle attack (MITM)

A Man-in-the-Middle (MITM) assault is also called an eavesdropping attack. In this attack, an attacker intercedes between two parties, i.e., the attacker hijacks the session between a client and a host. Hackers steal and modify data in this manner.

This happens when an attacker intercepts a two-way transaction and enters themself in the midst. Cyber intruders can then steal and modify data by disrupting traffic.

Since the victim believes the information is being delivered to a legitimate destination, this attack is complicated to detect. Phishing or malware attacks are frequently used to carry out a MITM attack.

Prevention:

Consider the safety of the website that you’re utilizing. Encrypt all of your devices.

Avoid utilizing public Wi-Fi networks.

Denial of Service attack (DOS)

DoS attacks function by servers, and networks with traffic, causing resources and bandwidth to become overloaded. The system cannot analyze and respond to user requests. There are distributed denial-of-service (DDoS) attacks in addition to denial-of-service (DoS) assaults.

TCP SYN flood attacks, teardrop attacks, ping-of-death attacks, and botnets are the most prevalent types of DoS and DDoS attacks.

Prevention:

To identify malicious traffic, perform traffic analysis. Recognize warning indicators such as network slowdowns, occasional website shutdowns, and so on.

DDoS protection should be outsourced to cloud-based service providers.

Zero-Day exploit

A zero-day exploit uses a newly discovered network vulnerability before a fix is available or applied. Zero-day attackers take advantage of the revealed vulnerability during the brief period when no solution or preventative measures are available.

Continuous monitoring, proactive detection, and agile threat management strategies are required to prevent zero-day attacks.

Prevention:

Patch management techniques should be effectively explained throughout organizations.

Prepare an incident response strategy to assist you in dealing with a cyberattack. Maintain a strategy on zero-day attacks.

Cryptojacking

Cryptojacking is closely related to cryptocurrency. It occurs when a hacker gains access to another person’s machine to mine bitcoin.

The attacker gains access by infecting a website or tricking the victim into clicking on a malicious link. Because the Crypto mining code operates in the background, victims are unaware of this.

Prevention:

Cryptojacking can infect even the most vulnerable devices, so keep your software and security apps up to date.

Employees should receive cryptojacking awareness training to assist them in spotting threats.

Password attack

Passwords are the most often used method of verifying access to a secure information system, making them a tempting target for cyber attackers. An attacker can acquire access to sensitive or vital data and systems by gaining access to a person’s password.

Password attackers employ various techniques to determine a unique password, such as social engineering, acquiring access to a password database, probing the network connection to retrieve plaintext passwords, or just guessing.

Prevention:

Use unique passwords for each website or account.

Update your passwords to reduce your vulnerability to a password assault.

There should be no password clues visible.

Cross-Site Scripting

A cross-site scripting attack inserts harmful scripts into legitimate websites’ content. The malicious code is added to the user’s browser’s dynamic range. This malicious code is typically composed of Javascript code performed by the victim’s browser, but it can also comprise Flash, HTML, and XSS.

Prevention:

On arrival, filter the input. Filter as precisely as feasible at the point where user input is received.

Firewall for web applications. A web application firewall (WAF) can be an effective solution for preventing XSS assaults.

Insider Threats

As the name implies, an internal hazard includes an insider instead of a third party. In such a circumstance, someone from within the company may know all about it.

Insider threats can do enormous harm. Insider dangers are challenging to forecast and, thus, difficult to manage.

Prevention:

Organizations should foster a security-conscious culture.

Companies must restrict the IT resources employees access based on their job duties.

Employees must be trained to detect insider threats.

How to Prevent Cyber Attacks

The complexity and variety of cyberattacks are constantly expanding, with a distinct form of attack for each evil aim. While cybersecurity prevention tactics vary depending on the type of assault.

  • Change your passwords regularly and use difficult-to-crack alphanumeric passwords.
  • Avoid using overly complicated passwords that you might forget. Do not use the same password more than once.
  • Update your operating system and programs regularly. This is the initial line of protection in a cyber-attack. This will eliminate weaknesses that hackers frequently exploit.
  • Use reliable and authentic antivirus protection software.
  • Use a firewall and other network security solutions such as intrusion detection systems, access control, application security, etc.
  • Open emails from unknown senders with caution. Examine the emails you receive for flaws and severe problems.
  • Authentication might be two-factor or multi-factor. Users must submit two distinct authentication factors to validate their identities with two-factor authentication.
  • We term it “multi-factor authentication” when you are asked for more than two additional authentication mechanisms in addition to your password and username.
