Network security has remained a major concern among CIOs for decades, but unfortunately enterprise security landscape is becoming increasingly complex despite several advancements in this field. The alarming growth of targeted attacks and cyber warfare implies the growing scale and sophistication of the offense, which could range from a common credit card scam to what could be considered as a serious national security threat. The advent of social media and mobility-driven initiatives has only aggravated the woes of CIOs, and so it calls for a comprehensive security strategy that ensures network security and endpoint security among millennial businesses.
Here’s a glimpse at the top five network security concerns faced by CIOs.
Data security over BYOD
Traditionally data loss has acquired the No.1 spot among security threats. The severity of the threat has only aggravated in recent years, thanks to the overwhelming growth in mobile devices. The ongoing mobility initiatives and the Bring Your Own Device (BYOD) strategy across enterprises have introduced new forms of security risks in their networks. The multitudes of free apps residing in users’ devices constantly interact with the network, making it vulnerable to security threats. Caught between the benefits brought by mobility initiatives and the dangers involved in inviting insecure devices, CIOs are required to enforce a robust mobile device management (MDM) and mobile security management (MSM) strategy to protect their networks against data breach.
The changing face of network intrusion
Network intrusion is a common network threat, but the scale has grown considerably in recent years making network intrusion detection difficult in many scenarios. The attack may appear as a Trojan, a malicious script or a traffic flooding that could result in Denial of Service (DoS) or gaining control of the network. While many CIOs are aware of the threats, the sly techniques used by criminals often challenge the IT’s ability to curb such attacks using traditional ways. For example, hackers nowadays employ techniques like deleting logs and installing rootkits to mask their network intrusion activity. Considering the severity of the situation, CIOs should seek a proactive approach to network security that will help monitor the networks for any such intrusion attempts and check them before they impact the IT.
Security of connected devices
The emergence of connected devices, aka Internet of Things (IoT), brings new security challenges arising due to mishandling of the associated apps or the communications networks. Most such instances occur due to vulnerabilities in apps and OS, as well as the casual approach of the users towards sharing their data across insecure Wi-Fi networks. With all these concerns to consider, data security is emerging as one of the toughest challenges ahead of IoT adoption in enterprises. Enterprises looking to exploit the IoT opportunities should seek strategies to safeguard IT from these vulnerabilities.
The Enterprise Everywhere concept created by cloud has changed the fundamentals of IT in organisations. However, the concerns over cloud security, especially those associated with the public cloud, have been a cause of worry among CIOs seeking a balanced approach with regard to the implementation and consumption of cloud. Ensuring endpoint security is crucial to protect the cloud network from malware. Cloud security specialists come to the rescue by offering a set of security solutions that prevent unauthorised network access, spams, Trojans, and more.
The connected millennial today is engaged in exchanging data over internet during most part of their day in office or at home. The security and authenticity of the apps and the websites they interact with may not be verified all the time. With mobile devices taking over laptops and desktop PCs for information exchange, the chances of security threats are multifold. The fact that majority of mobile phones and apps are not protected by antivirus or internet security tools now calls for the need to secure enterprise networks from such vulnerabilities. When traditional antivirus or antispam solutions do not suffice, there is a need to adopt a unified approach to security to address the multiple levels of threats emerging from different use cases.
Unified Threat Management (UTM) is emerging as the best practice to network security. By offering comprehensive security in the form of content filtering, anti-spam capabilities, anti-virus protection, data protection, WLAN security, network intrusion prevention, and more, UTM empowers enterprises with robust IT capabilities to thrive in the digital era.
