What is cybersecurity? Its importance and Types of cyber threats!

Cyber security is a process used to protect sensitive data, hardware, and software from unknown and malicious threats. Data sensitive and financial organizations mainly follow cybersecurity protocols to restrict unauthorized access from causing trouble to their digital workflows. Statistics show that in 2020, there were a total of 1001 cases reported for data breaches in the US. 

A robust cybersecurity approach can ensure better protection from suspicious attacks specially designed to modify, update, or delete users’ or organizations’ confidential data. Cybersecurity practices are pretty helpful for deterring attacks that disable or harm the system.

Why is cybersecurity necessary?

With the rapid increase in users and data flow across the digital space, it is more important than ever to incorporate stronger cybersecurity protocols to prevent sophisticated cyberattacks from invading system vulnerabilities.

Same cybersecurity threat but different forms!

Maintaining new technology, security trends, and threat information is a complex undertaking, and it takes a lot of time and effort. It is required to secure information and other assets from cyber threats, which may take on many different forms. The following are examples of cyberthreats:

1. Malware is harmful software that may exploit any file or program to damage a computer user. Malware is classified as a type of malicious software. Worms, viruses, Trojan horses, and spyware are examples of malware.

2. Ransomware is a sort of software that demands a ransom payment. Attackers often encrypt and lock the victim’s computer system files and then demand money to decode and unlock the data once they have been locked.

It is a kind of attack that depends on human contact to fool users into violating security processes to obtain sensitive information usually kept confidential.

3. Phishing is a kind of social engineering in which fake email or text messages are sent that seem and sound like they are coming from reputable or well-known sources. The objective of these communications, which are often random assaults, is to steal vital information, such as credit card or login information.

4. Spear phishing is a sort of phishing assault designed to target a specific person, organization, or company.

5. Insider threats are security breaches or losses caused by people — such as workers, contractors, or customers — rather than by malicious software. Insider threats may be malevolent or careless in their behavior, depending on the situation.

6. Denial-of-service (DDoS) attacks are when numerous systems work together to prevent traffic from reaching a targeted approach, such as a server, website, or another network resource, from being delivered. When an attacker floods a target system with messages, connection requests, or packets, they may cause the system to slow down or even crash, preventing legitimate traffic from making use of it.

7. Advanced persistent threats (APTs) are targeted assaults over a lengthy time in which an attacker gains access to a network and stays undiscovered to steal data.

8. Eavesdropping attacks that include an attacker intercepting and transferring communications between two parties that think they are speaking with one other is known as man-in-the-middle attacks (MITM attacks).

What is the impact of Artificial Intelligence on cybersecurity?

Automation has evolved into a critical component of keeping businesses safe from the expanding quantity and complexity of cyberthreats, becoming more sophisticated. The usefulness of artificial intelligence (AI) and machine learning algorithms in areas with large amounts of data may aid in the improvement of cybersecurity in three major categories:

1. Detection of potential threats. Artificial intelligence systems must examine data and detect current threats to identify and forecast fresh dangers.

2. Response to a threat. Security safeguards are also created and implemented automatically by AI systems.

3. The use of human processes enhancement. Security professionals are often burdened with many warnings and repetitive activities. The use of artificial intelligence may assist in reducing alert fatigue by automatically triaging low-risk warnings and automating extensive data analysis and other repetitive operations, allowing them to devote their time to more complex duties.

Additionally, automation in cybersecurity may help with attack categorization, malware classification, and traffic and compliance analysis, among other things.
