Cyber Network Security: Key Insights for Singaporean IT Professionals

Key Types of Cyber Network Security  – Deep Understanding for Singaporean IT Professionals

The Singapore Cybersecurity Agency (CSA) has reported a rise in cybercrimes, including phishing, ransomware, and scams, with e-commerce fraud reaching 21.3 million Singapore dollars in losses in 2022.  Awareness alone is not enough. Businesses must implement and maintain strong network security solutions to protect against these threats. Key types of cyber network security are essential knowledge for Singaporean IT professionals to ensure robust protection.

Access Control

Access control is a crucial element of cyber network security that regulates who can access specific data, applications, and resources. It ensures that only authorized users can enter while keeping unauthorized individuals out. For instance, administrators may have full network access, whereas personal devices are barred from confidential areas. Instead of manual management, organizations use identity and access management (IAM) solutions.

Access control relies on two main techniques: authentication, which verifies user identity, and authorization, which determines access levels based on factors like device, location, and role. 

This method is vital for protecting sensitive information, such as customer data, from unauthorized access. Vulnerable databases often store such data, making it a target for identity fraud. Javelin Strategy & Research reported that identity fraud losses reached USD 24 billion in 2021, a dramatic 79% increase from 2020.

Antivirus and Anti-Malware Software

Comprehensive protection in cyber network security demands constant vigilance against malicious software. This involves deploying security measures such as antivirus and anti-malware programs, which are designed to detect, eliminate, and block viruses, trojans, ransomware, and spyware from compromising computers and, by extension, the entire network. 

To ensure data is properly secured, these tools must not only scan files as they enter the network but also provide ongoing monitoring of all files within the system.

Users should keep their software up to date and regularly scan their devices to ensure no malicious activities or programs go undetected. Additionally, they should stay alert to phishing attempts and other hacking methods by implementing security practices such as two-factor authentication and strong passwords.

Cloud Security

Over the years, both individual users and businesses have increasingly adopted cloud technology, leading to vast amounts of data being stored in the cloud. However, this shift has made the cloud a prime target for cyber-attacks. The number of vulnerabilities is rising, with ethical hackers uncovering approximately 65,000 vulnerabilities in 2022 alone, marking a 21% increase from 2021, according to the HackerOne 2022 “Hacker-Powered Security Report.”

Cyber network security in the cloud encompasses a wide array of tools and practices, but the cornerstone is access control—ensuring that only authorized users can access data stored in the cloud. Key tools for security in the cloud include:

• Data encryption
• Data segmentation
• Threat monitoring and prevention
• Firewalls
• Identity and access management (IAM)

Firewalls

A firewall is a crucial element of cyber network security, designed to monitor and filter both outgoing and incoming network traffic according to an organization’s established security policies. Simply put, a firewall acts as the barrier between your private intranet and the public Internet.

As an integral part of any network system, firewalls serve as a defensive shield, protecting the network from external threats. When configuring network firewalls, it’s essential to define specific rules and permissions that determine who can access the network.

Maintaining an updated firewall with well-defined policies provides an additional layer of defense against cyber-attacks that aim to exploit vulnerabilities within the network infrastructure.

Main Cyber Network Security Levels

Depending on an organization’s size, financial resources, the type of information it handles, and whether it operates in a regulatory or non-regulatory industry, there are three main levels of cyber network security protection in the Singapore market. It is advisable to consult with your IT department or a cybersecurity services provider to determine the level of protection that best fits your business’s cybersecurity needs.

Level 1 – Minimal Protection

If you run a small business that does not handle sensitive client data, operates in a non-regulatory sector, or has a tight budget, the first level of cyber network security protection is suitable for you. This level focuses on defending against common security threats like phishing, malware, and spoofing attacks.

For minimal protection, you should implement a properly configured firewall and regularly updated antivirus software. Your IT department can manage these security measures. Additionally, conducting regular application security assessments is crucial to guard against malicious code and vulnerabilities. Annual vulnerability assessments and penetration testing will help system administrators identify and address any security weaknesses in your network.

Level 2 – Advanced Protection

Level 2 cyber network security focuses on defending the corporate network from non-targeted attacks such as malware sent to multiple email addresses, phishing attempts, and spamming. Attackers in this scenario aim to exploit any IP address vulnerable to known security flaws within the network.

Medium-sized companies are often vulnerable to cyber-attacks because they may not adhere to strict security standards and might neglect advanced network security solutions. Beyond basic security measures, advanced protections include email security, network segmentation, intrusion detection systems (IDS), and intrusion prevention systems (IPS).

At this stage, it is crucial to have an information security expert to manage these tasks. Businesses should also develop a comprehensive security strategy that includes quarterly vulnerability assessments and annual network penetration testing to identify, address, and manage cybersecurity risks. Additionally, companies need to consider the security implications of staff using personal devices for work and the use of cloud computing.

Level 3 – Maximal Protection

Organizations in regulated industries such as banking or healthcare need robust cyber network security to defend against targeted attacks aiming to steal sensitive data. Midsize and large enterprises must adhere to industry regulations and implement key cybersecurity components:

• Endpoint Security: Software installed on devices like laptops and smartphones to protect corporate networks from threats, providing real-time visibility of potential risks.
• Data Loss Prevention (DLP): Essential for safeguarding sensitive data by controlling and protecting data transfer outside the corporate network, preventing unauthorized email forwarding and file uploads to cloud storage.
• Security Information & Event Management (SIEM): Collects and analyzes IT activity data to prevent hacking, centralizes log data, and ensures compliance with regulations for real-time incident response.

At this level, organizations need a dedicated information security department and a managed security service provider (MSSP) for the effective operation of security solutions. A detailed service-level agreement (SLA) with a cybersecurity services company provides 24/7 monitoring and cost reduction. 

Key measures include developing a comprehensive security strategy, conducting vulnerability assessments and penetration testing, constant threat monitoring, and a structured incident response plan. Effective threat monitoring is crucial, especially with remote work, and a dedicated in-house or outsourced team like Orient Software can help prevent small issues from becoming major problems like data breaches or system outages.
