Cyber Threats: The Unavoidable Reality and Cybersecurity Measures for Businesses


The vital role of cybersecurity in the age of digital transformation cannot be emphasised. The temptation for cybercriminals grows tremendously as firms transfer more operations online and store enormous volumes of sensitive data digitally. Furthermore, the regrettable tendency of Australian corporations to pay ransoms to cyber criminals has unintentionally fueled the cybercrime sector. As a result, businesses have to understand but also manage cybersecurity threats proactively. Plex IT offers a deep dive into essential cybersecurity terms, concepts, best practices and cybersecurity measures for businesses to assist you in navigating this complicated world. As an IT managed service provider our mission is to empower you to make educated decisions that improve your organisation’s cybersecurity posture.


The Cybersecurity Lexicon: Understanding Key Terms and Concepts


What Exactly Are Attack Vectors?

An “attack vector” is simply a way or method for a hacker to obtain unauthorised access to your computer system. Understanding these vectors allows you to protect your company better. Because knowledge is your first line of protection, become acquainted with terminology like phishing, malware, and social engineering, which represent many attack vectors.

The Good, the Bad, and the Ugly of Bugs and Vulnerabilities

Bugs are unavoidable in software development. These are the flaws or mistakes that developers run into while developing an application. However, not all bugs are dangerous; it is the “vulnerabilities” that you should be concerned about. Vulnerabilities are unique bugs that can be exploited to compromise the security of your system. Regular updates and patches help address known vulnerabilities, but staying vigilant is essential for detecting new threats.

The Silent Threat of Zero-Day Vulnerabilities and Exploits

Zero-day vulnerabilities are security flaws unknown to the vendor and, as a result, unpatched. A zero-day exploit is an attack that exploits such a vulnerability. These are especially harmful because there is no approved remedy during the exploit. To combat these sneaky threats, businesses must implement specialised security solutions such as behaviour-based detection systems.

Phishing: More Than Just Fake Emails

While email phishing is common, other forms of phishing, such as spear phishing, vishing (voice phishing), and smishing (SMS phishing) are also prevalent. Awareness and employee training are your most robust defences against these socially engineered attacks.

The Human Factor in Social Engineering and Identity Theft

Social engineering leads people to violate usual security standards, frequently resulting in identity theft. This could include mimicking a target’s colleague or a family member. Understanding the subtleties of these assaults might assist you in creating a cybersecurity culture within your firm.

Malicious Payload: The Destructive Component

The “malicious payload” is the malware component that causes the harm. This could include destroying files and sending illegal emails to encrypting your data and holding it for ransom. Malware, viruses, and ransomware are all examples of malicious payloads to be mindful of.

Subtypes of Malicious Payloads

  • Malware: General term for malicious software.
  • Viruses: Malware that replicates by infecting other files.
  • Ransomware: Encrypts your data and demands a ransom for release.
  • Exfiltration: Unauthorised data transfer, often used in corporate espionage.

Distributed Denial of Service (DDoS) Attacks: The Floodgates are Open

DDoS attacks try to disrupt an online service by flooding it with excessive traffic. DDoS assaults are classified into numerous types:

  • Volumetric Attacks: Overwhelm a network with sheer data volume.
  • Protocol Attacks: Take advantage of flaws in network protocols.
  • Application-Based Attacks: Prey on specific application flaws.


Proactive Cybersecurity Measures for Businesses


Perform a Risk Assessment

The first step in developing a solid cybersecurity plan is identifying your vulnerabilities. A thorough risk assessment will reveal potential gaps in your system, allowing you to deploy resources better.


Make use of firewalls and web application firewalls (WAFs).

These are your critical barriers to unauthorised entry. WAFs give more targeted security at the application layer, whereas firewalls manage traffic between your network and external networks.


Use Penetration Testing and Vulnerability Scanning

These strategies aid in the detection of vulnerabilities in your systems. Penetration testing uses simulated cyber-attacks, whereas vulnerability scanning employs automated methods. Each has advantages and disadvantages, but both are necessary for a comprehensive cybersecurity plan.


Antivirus and EDR: Beyond the Basics

Endpoint Detection and Response (EDR) solutions go beyond typical antivirus software by studying the behaviour of software operating on network endpoints. This advanced capacity is becoming increasingly important to guard against complex threats undetectable by regular antivirus solutions.


What You Need to Know About Regulatory Obligations


Critical Infrastructure companies in Australia must disclose cybersecurity issues to the Australian Cyber Security Centre (ACSC) within 12 hours. This assists the ACSC in addressing the incident and taking actions that benefit impacted clients, such as arranging identity document replacements.

In addition, the Notifiable Data Breaches (NDB) scheme requires any organisation or agency covered by the Privacy Act 1988 to notify affected individuals and the OAIC when a data breach is likely to cause substantial harm to an individual whose personal information is implicated.
