In Security

The word ‘Malware’ is derived from the amalgamation of words malicious and software. It is a type of software that is particularly designed with the sole purpose of harming a target computer system by stealing data or causing disruption. In order to stay protected against malware, companies need to use specific anti-malware programs. But before choosing the correct anti-malware system, it is imperative to know about different types of malware.

Following are some common malware types:

  • Virus: A computer virus is malicious code that has the ability to copy itself and spread to other files and folders. The code attaches itself to legitimate executable programs resent in the target system and launch when the program is executed. Some of the harmful functions performed by viruses are modifying or corrupting files, copying data, disrupting software functions, etc. As the virus is self-replicating, it is difficult to completely remove the virus completely.
  • Worms: Worms are self-replicating and infect computers through vulnerabilities in the operating systems. Most worms are designed to consume lot of bandwidth and overload the servers. However, small number of worms can modify the existing files. Worms are used by the hackers to deliver payloads in target systems which are then launched to steal data, corrupt files, etc.
  • Bot: An internet bot is an application designed to perform automatic functions. Hackers can engineer bots to infect computers and perform large scale DDOS attacks. The bots are programmed to infect multiple computer systems and form a botnet to over-flood the server with a large number of requests. Bots are also used to cause inconveniences like spamming and repetitively showing certain advertisements.
  • Ransomware: Ransomware is a malicious software that completely locks the infected system until the user pays a ransom. Ransomware spreads like a worm across a network and has the ability to infect the network of an organization within hours. Some ransomware software do not lock the entire system, but encrypt critical data files. The users are asked to pay a ransom in exchange of decryption key.
  • Spyware: It is a software that lies undetected in the target system. It’s purpose is to collect information on user activity and send it to the hacker’s server. This is done by monitoring usage, logging keystrokes, stealing user passwords, etc.
  • Trojans: A Trojan is a malicious software that is designed to appear as a common, harmless attachment or downloadable file that may not be detected as harmful by the antivirus system. However, once downloaded, the software executes itself and causes damage such as stealing data, erasing or modifying files, altering system configuration, etc.

Detection Of Malware:

Some common signs that indicate presence of malware are:

  • Slowing down of systems
  • Reduced browsing speed
  • Recurrent freezing of systems
  • Modification of files
  • Altered system settings
  • Missing files
  • Random appearance of new files or applications

Prevention Of Malware:

  • Use reliable & authentic anti-virus
  • Conduct regular scans
  • Do not use pirated software
  • Don’t open attachments from unknown sources

Cyber-crime environment is constantly evolving and cyber criminals are always trying to come with new types of attacks for outsmarting existing cyber security protocols. This emphasizes on the need to recognize and deploy advanced cyber security measures to combat cyber threats effectively.

Here are some reasons that strengthen the need for organizations to invest in advanced cyber security technologies:

  • Cyber-attacks are no longer targeted at merely extracting confidential details or earning quick money. They have moved on to more sinister motives, commonly known as cyber warfare. With increasing connectivity among critical utility infrastructure, cyber warfare has a tendency to grow.
  • Cyber criminals are getting more advanced and the number of sophisticated cyber-attack tools is growing in the deep and dark web.
  • Most organizations keep business-critical data recorded in digital format and are thus greatly dependent on their systems and network. Failure to secure these systems from cyber criminals can endanger credibility, sales, and profit.

Owing to the heating up cyber warfare, organizations need to identify and adopt emerging cyber security technologies constantly. Following is a list of top advanced cyber security technologies that businesses organizations should adopt:

  • Artificial Intelligence & Deep Learning: Application of artificial intelligence in cyber security is similar to two-factor authentication. Two-factor authentication confirms user’s identity based on two different parameters. Artificial intelligence adds additional layers of information and authentication to identity confirmation. Deep learning is used to analyze data such as logs, transactions and real-time communications to detect threats trying to penetrate the system or network.
  • Behavioral Analytics: Behavioral analytics uses data mining techniques to determine patterns of activity across a system and network. This helps in detecting unusual activity such as abnormal increase in data transmission from a device connected to the network. Such deviations from normal pattern can be used to detect potential and real-time cyber threats.
  • Embedded Hardware Authentication: A PIN and password are no longer sufficient to protect hardware, so embedded authentication chips are being used to secure hardware. These powerful chips such as Sixth-generation vPro chips by Intel are embedded in the hardware. The chips employ multiple levels and methods of authentication that work in tandem to ensure authentication security.
  • Blockchain Cyber Security: Blockchain cyber security works on the basis of blockchain’s peer-to-peer network fundamentals. Every member in the blockchain is responsible for verifying the authenticity of data added. It creates a near-impenetrable network to secure organizational data.

In Networking

The importance of data in business growth is imperative; however, network holds equal importance as it facilitates the flow of data. This makes it important to secure the organizational network to protect data as well as secure network endpoints. Thus, organizations need to implement effective network security and network visibility strategy.

Here is a list of network security tools that can help organizations in securing their network against security attacks:

  • Access Control: The best way to control damage caused by threat actors is to keep them out of the network. In addition to limiting the access of outside threats, it is equally important to take care of insider threats. Access control tools help organizations in keeping out threat actors and limiting user access to network areas that directly apply to user’s responsibilities.
  • Anti-Malware Software: Malware including virus, trojans, worms, keyloggers, spyware, etc. are designed to spread across computer systems and infect an organization’s network. Anti-malware tools assist organizations in identifying, controlling and resolving malware infections to minimize the damage caused to network.
  • Anomaly Detection: In order to detect anomalies in a network, it is first important to understand usual operations of the network. Network security tools such as Anomaly Detection Engines (ADE) allow organizations in analyzing a network, so that when and if any anomaly or network breach occurs, the IT team will be alerted quickly enough to limit the damage.
  • Application Security: Most cyber attackers consider applications to be a defensive vulnerability that can be exploited to cause network disruptions. Including application security tools can help organizations in establishing security parameters for applications.
  • Data Loss Prevention (DLP): Threat actors tend to use humans to cause data breach or network security breach. DLP technologies and policies help in protecting the employees and other users from misusing or possibly compromising sensitive data or allowing data flow out of the network at any of the endpoints.
  • Email Security: Email security tools are another set of network security tools that help organizations in minimizing human-related security weaknesses. Hackers or cyber criminals persuade employees to share sensitive information or inadvertently download malware into targeted network via phishing strategies. Email security tools assist organizations in identifying dangerous emails and blocking attacks.
  • Endpoint Security: Bring Your Own Device (BYOD) culture has become highly integrated in organizations to an extent that it has become tough to distinguish between personal and business devices. Cyber attackers take this as an opportunity and attack personal devices to launch a network security attack. Endpoint security tools add a layer of defense between remote devices and business networks.
