In the current threat landscape, data breaches are rapidly becoming the new norm. This makes robust IT security critical to secure company and customer data.
According to the Office of the Australian Information Commissioner (OAIC), malicious cyber attacks remained the leading cause of data breaches, accounting for 61% of all data breach notifications in the first half of 2020.
Furthermore, human error accounted for as much as 34% of all data breaches in the country. This suggests that enterprise security’s far more complicated than just obtaining sensitive data or protecting it.
Today, managed IT services providers help small and medium-sized enterprises and corporations access top security talent and technologies to fortify their IT infrastructure, cost-effectively. This approach allows IT support teams to leverage various cybersecurity protocols to protect sensitive, personally identifiable information and maintain business relevance.
IT Security Defined
IT security incorporates a set of cybersecurity strategies to prevent unauthorised access to enterprise assets such as servers, networks, and data. It helps ensure data privacy and compliance by maintaining the integrity and confidentiality of sensitive information (by blocking the access of sophisticated hackers).
It’s essential as bad actors are relentlessly attacking enterprise networks. So with the help of managed IT services, security teams must strive to mitigate multiple cyber threats like the following:
- Denial-of-service attacks
- DNS tunnelling
- Malware attacks
- Phishing campaigns
- Ransomware attacks
- SQL injection
- Zero-day exploits
Different Types of IT Security
There isn’t a fool-proof turnkey security solution that can alleviate multiple threats to enterprise networks in this rapidly evolving threat landscape. To mitigate risk, companies must evolve with the threat and implement a multi-pronged approach to secure their technology infrastructure.
This process starts with the individual evaluation of different cybersecurity layers:
Application security focuses on security at a development level. This approach demands adequate security protocols coded into applications to eliminate any potential vulnerabilities.
For example, a zero-day attack is initiated when hackers hunt for vulnerabilities to exploit and find one. So applications are now thoroughly evaluated during the development cycle to identify and fix any of the app’s potential weaknesses.
Today, organisations take it a step further by engaging in manual penetration tests, black-box analysis, white-box analysis, and more to identify potential flaws missed by internal security teams.
Cloud security protocols help secure enterprise applications and users on the cloud. Whether it’s a public, private, or hybrid cloud, companies must deploy a variety of technologies to better secure their environment.
Some cloud security tools deployed by companies include:
- Cloud-Access Security Broker (CASB)
- Cloud-Based Unified Threat Management (UTM)
- Secure Internet Gateway (SIG)
While the technologies above help protect the cloud, businesses must also implement robust encryption protocols to protect data in motion and rest.
Of all the different IT security protocols, endpoint security is probably the most challenging threat to mitigate. This is because end-users often don’t follow the same security best practices and jeopardise the entire network (often through human error).
With endpoint security, IT security teams must strive to secure every entry point to the network, whether it be computers, mobile phones, or the Internet of Things (IoT). This is not straightforward and often demands extensive third-party IT support to fill the talent gap.
To achieve robust endpoint security, security leaders must also demand regular security training workshops and technologies like sophisticated anti-malware software, encryption tools, and Virtual Private Networks (VPNs).
Network security is leveraged to block malicious users from breaching the network while ensuring enhanced usability, reliability, and uncompromising integrity. It’s the most common form of IT security deployed to deny unauthorised access to data generated within the network.
This approach helps ensure enhanced user experiences while maintaining robust security. In this scenario, security teams use endpoint security protocols along with antivirus software, firewalls, and Intrusion Detection and Prevention Systems (IDS/IPS) to strengthen their security posture.
As technology continues to grow more advanced and scale, maintaining robust IT security has become a game of cat and mouse. As hackers discover ever more ingenious ways to exploit vulnerabilities, security teams must adapt to the changes and strive to stay a step ahead of threat actors.
