Cybersecurity Essentials: Threats to Data in a Digital Age

We are living in the digital age. The Internet & social media have made availing & accessing information a simple task. The wide availability of personal electronic devices and the Internet, an ever-increasing dependency on digital services, and the adoption of digital infrastructure have all resulted in prominent digital footprints. Digitization has put petabytes of sensitive information out there in the virtual space beyond the control of its original owner. And therein lies the problem. Since the rise of digitization, numerous devastatingly damaging cyberattacks have occurred through the years. The 2012 attack on Saudi Aramco, the 2013 Yahoo hacks, the 2014 iCloud hack,  the 2021 Colonial Pipeline ransomware attack – the list goes on. The only surefire way of monitoring, preventing, and countering such damaging cyberattacks is by implementing state-of-the-art cybersecurity measures.

The cybersecurity industry is a critical component of the digital and IT sector. Expected to surpass USD 691.64 billion by 2032, cybersecurity is also an exceptional career choice for the tech-minded individual. If you, too, are looking to master cybersecurity and make a career out of it, then, a leading expert assignment help service from the USA, is here to help you out.

Read on for some amazing insights on cybersecurity essentials.


Key Cybersecurity Terms

There are different types of security breaches in the digital domain. Each is unique, can use different technologies, and takes advantage of different security lapses or vulnerabilities.

  • A vulnerability is a weakness, loophole, limitation, or flaw in a digital system that attackers can exploit.
  • Threats are circumstances that create the potential for a vulnerability to be exploited.
  • An attack is the exploit of a vulnerability by a malicious agent.
  • Countermeasures can be different and generally involve steps to counter a cybersecurity attack and/or shore up system resiliency to prevent further attacks.

Given the vast variety of information stored in digital systems, the motivation and objectives behind a cyberattack can vary widely. However, the endgame of most cybersecurity attacks is to gain unauthorized access to information, disable digital infrastructure, and/or inject malicious codes.

Cybersecurity encompasses a set of principles, strategies, techniques, and technologies designed to safeguard systems and assets against threats. Vast, complex, and particularly nuanced, cybersecurity employs concepts from different formal science disciplines to design systems for monitoring, preventing, and countering cyberattacks.

Types of Cyberattacks

  1. Malware

Malware or malicious software is any malicious software, program, or code designed for nefarious purposes. Malware attacks are very common and have bene used for stealing information, circumventing security measures, revealing loopholes, disabling systems, and/or denying services. Viruses, Trojans, spyware, worms, adware, keyloggers, bots, and crypto-jacking software are some of the most common types of malware.

  1. Denial-of-Service (DoS)

These targeted attacks overwhelm networks or systems, resulting in widespread disruption of operations/services. DoS prevents authorized users from accessing and availing routine tasks. While they generally do not cause any data loss, the disruptions caused by DoS attacks lead to substantial losses of time, money, and other resources. Disruptions can wreak havoc, especially if they target critical infrastructure such as banks, payment, and healthcare.

Distributed denial-of-service attacks (DDoS attacks) are a variation of DoS attacks and are faster and more challenging to block and resolve. While DoS attacks normally originate from a single system, DDoS attacks occur from multiple sources.

  1. Phishing

Phishing lures the unwary into revealing sensitive information. The process involves sending fraudulent information from sources masquerading as or mimicking reputed sources. Phishing websites and applications look strikingly similar to the original ones and have systems for stealing sensitive data such as credit card or login information, installing malware, etc.

  1. Spoofing

Spoofing is similar to phishing in that cybercriminals masquerade to mislead the vulnerable. They masquerade as a reputed or trusted source to steal information, reveal and/or create vulnerabilities, install malware, etc.

  1. Code Injection

As the name suggests, code injection attacks involve inserting malicious codes (not malware) into a system. They are generally stealthy and can disrupt normal operations, modify and steal information, and cause other damage. SQL injections and cross-site scripting are two common examples of code injection-based attacks.

SQL injection involves injecting codes into SQL databases, generating unauthorized queries and data extraction, deletion, modification, etc.; cross-site scripting injects harmful codes into legitimate websites that attack systems visiting the infected website.

  1. Identity-Based Attacks

These attacks used compromised identities and are very hard to detect & discern. Stolen user credentials allowed criminals to masquerade as someone else, resulting in exposure, modification, and theft of valuable information.

  1. DNS Tunnelling

These attacks eavesdrop on domain naming system (DNS) queries to bypass established security measures. If infected with DNS tunneling malware, attackers can divert the unwary to malicious sites and wreak further havoc. Criminals can gain remote access to execute command-and-control activities on a system, unleash malware, and modify & steal information. Simple to carry out, DNS tunneling attacks have increased alarmingly in the past few years.

  1. IoT-based Attacks

The Internet of Things is a consequence of rapid digitization. These attacks target particularly vulnerable devices and, if successful, can access an entire network of connected devices. With the sudden rise of Internet-enabled IoT devices, there has also been a steady rise in IoT attacks and infections.
