A Look At The emerging  Cyber-Threats

Why are cyber-attacks on the rise?

It's because cyber attacks are less expensive, more convenient, and less dangerous than physical ones. Aside from a computer and an Internet connection, cybercriminals just require a few expenses.

They aren't bound by territory or distance.

Because of the anonymous nature of the Internet, they are difficult to identify and prosecute. Given how appealing attacks against information technology systems are, it's likely that the quantity and sophistication of cyber-attacks will continue to rise. Understanding the issues surrounding various cyber threats and implementing defense tactics (i.e., countermeasures) that preserve the confidentiality, integrity, and availability of any digital and information technology are all part of cyber security.

  • Confidentiality refers to the protection of information from being disclosed to unauthorized people or systems.

  • Integrity refers to the ability to avoid unwanted changes or deletions.

  • Availability refers to the ability of systems responsible for transmitting, storing, and processing data to be accessed when and by people who require them.

Malware attacks have traditionally occurred at a single point of entry among hardware, software, or network components, exploiting existing design and implementation weaknesses at each layer.

Rather than defending each asset, the perimeter defense technique has primarily been employed to construct a wall around all internal resources to secure everything within from outside intrusion.

Firewall and anti-virus software placed within intrusion prevention/detection systems are used by the majority of perimeter defense mechanisms.

Any traffic coming in from the outside is captured and inspected to ensure that no virus has infiltrated the internal network. Phishing is a technique for obtaining sensitive information such as usernames, passwords, and credit card numbers by impersonating a trustworthy institution.

The majority of phishing scams work by tricking a user into accessing a malicious website that pretends to be from a reputable company or agency.

An unsuspecting user provides personal information on a fraudulent website, which is then used by malicious criminals. Once the malware has been installed on a victim's system, cybercriminals can exploit a variety of existing vulnerabilities in the victim's system to enhance their illegal activities.

We look at the most widely exploited security flaws in hardware, software, and network systems. Following that, there will be a discussion of present and proposed attempts to ameliorate the negative effects of the exploitations.

Cyber attacks against cyberspace evolve with time, taking advantage of new techniques. Most of the time, cyber thieves would change existing malware signatures to take advantage of holes in new technology. In other circumstances, they just investigate the specific qualities of new technology to uncover gaps via which malware might be injected.

Cyber thieves take advantage of new Internet technologies that have millions or billions of active users to reach out to a large number of victims fast and efficiently.
