In today’s interconnected world, cyber-attacks have become a threat to the entire cyber world. A massive amount of confidential data is stored and processed on computers and are being transmitted that information across networks to other computers by the Government as well as the private individuals.

In this regard of ongoing increase of cyber-attacks, due attention has to be given to protect sensitive business and personal information, thus safeguarding national security. Cyber security now has become a big deal as people have begun to worry about cyber security risks. Cyber security is sometimes referred to as Information technology security, focusing on securing and managing computer programs, networks and data from any unauthorized access.

It is in contrast to a malicious hacker who hacks a computer with the intent to steal private information or cause harm to others. Cyber security prevents such malicious and unauthorized access establishing or significantly bolstering varieties of blockers or firewalls or practice groups in cyber security law. There are several types of cyber attacks which weaken and provides a threat to safety systems of several organizations by infringing their secrecy norms, most common types of cyber attacks; hacking, IPR infringement, Cyber terrorism, etc. making every enterprise a potential victim.

Types of Cyber Attacks

There are many techniques taken for use by the lawbreakers, from virtual sit-ins, website defacement, and parodies, to a more extreme method such as information theft, web site sabotage and denial of service attacks. Apart from the attacks mentioned herein before, there are several other avenues of attack or types of cyber attacks that a victim can fall. Since they put their base on general hacking coupled with the denial of service, it is prudent to discuss this method first.

1. Denial of Services (DoS)

A DoS attack involves an effort that focuses on the disintegration or interruption of a network service. It is a form of cyber-attack which makes one or more computer systems unavailable. In this type of cyber attack typically the central server is targeted from where an attacker generates and sends high rates of traffic or data through the central server until the network becomes overloaded.

Because of such overloading, it affects those resources of a computer which needs to function such as network bandwidth, memory and disk space, data structures and access to other networks. DoS attacks and disturbs networks, depending on the nature of the enterprise, thus capable of disabling an organization.

2. Password Attacks

These attacks involve cracking a user’s password to get access to a secured system. The attackers use software to try and crack user’s password, but this software they use is usually run on their system. It consists of many ways to ascertain passwords, including brute force attacks which are made to guess passwords.

Brute Force Attack is usually used to discover or crack a complicated password. An automated software is taken in use to generate multiple opinions as to the value of the desired data. It is one of the common threat among the other types of cyber attacks because it is used by hackers or may be used by criminals to decode encrypted data. Any password can be revealed using the brute attack, but it can take a very long time to complete. A user can prevent such attacks by keeping a secure password, the only safeguard against such threat. It is also recommended to change your password at regular intervals so as to minimize the risk of getting hacked.

3. Malware

It is a term used for covering a variety of threats in this cyber world which commonly includes socially engineered Trojans, viruses, and worms. It often introduced to the system through emails or external storage devices or any downloads from uncertified sites. Malware is commonly used to destroy something on a system or to steal private information which is highly confidential.

It gets introduced to a system through software downloads or operating system vulnerabilities. The optimal way to prevent malware is avoiding links which pop out from unknown senders or by avoiding downloads from uncertified sites.

4. Phishing

It is an attempt to ascertain fragile information such as username and password, often for malicious purposes by pretending as trustworthy being in communication. It is one of the examples of social engineering techniques for deceiving users and due to their poor knowledge of current web security technologies often exploit them.

As it mostly includes links to redirect to malicious sites it has become a significant threat nowadays since attackers now also develop dummy sites to acquire usernames and passwords.

Conclusion

The use of computers and the Internet have been increasing for several decades and have become an indispensable tool in the recent era. As they continue to evolve at increasingly rapid pace, these modern technologies are certain to play a significant role in days to come. However, this new technology is largely uncontrolled and unregulated which is why some have begun to declare it a major threat to this era.

Every technology and invention have its advantages and some disadvantages too, while some talk about benefits of preserving current internet’s uncensored state whereas on the other hand others defined such state as a breeding ground for potential criminal activities. The technologies which are now threats were once made to serve a legitimate purpose but later it lost its way.

Although there are numerous threats on the scene, preventive measures have also been provided preventing such attacks. The users have to compromise because there is no set form for technologies and to fill this lacuna cyber security has been made flexible with the advancement of technologies.
