By 2024 there will be roughly 200 billion connected devices, according to the Washington Times. All these devices will rely on various networks to share data. With the increasing number of interconnected devices and computers, network security has become instrumental.
In an organization, securing the network is your first line of defense against external and internal threats. Without a secure network, cyber intruders can employ a wide array of methods to launch crippling attacks on your organization. To keep it safe, you need to be aware of the current threats. Here are some network security threats you need to prepare for.
Employee Error
Sometimes, even your most devoted and trusted employee can cause security threats. They may unknowingly perform a risky action, take security measures too lightly, or blatantly disregard the rules. Such insider threats may be difficult to notice since most organizations focus on tackling external security challenges.
To mitigate against employee risks, you need to take some measures. Start by training all your employees how to detect an attack, what action they should take, how to store sensitive data, and how to protect your company from threats. To learn the activities of employees on the network in real-time, you can utilize a log monitoring software. To educate yourself or get more details about these tools, check out the reviews.
BYOD Security Risks
Bring-your-own-device (BYOD) programs have become very popular nowadays. Thanks to BYOD policies, companies no longer have to invest in expensive devices, employees are now more productive, and they are able to work with more flexibility. Sadly, this policy has imposed a major burden on the network security systems.
Data leakage is a real threat when personal devices are allowed to access an organization’s data. The device can be stolen, attacked by malware, be used to connect to questionable outside networks, or be installed with patchy apps which can be exploited by hackers. For safety, companies need to develop and enforce a BYOD policy.
Wired Network Threats
Since most organizations are occupied with protecting their wireless networks, they leave their wired ones exposed. To protect your wired side of the network, start by physically protecting your building and mapping all your network’s infrastructure and your cables’ connectivity path across it.
Mapping ensures you have a clear and updated record of all access and endpoints, account for all cables, and know all connected equipment and systems. An audit can also help you discover settings that are wrongly configured or an exposed ethernet wire that can be physically used by hackers to compromise your security. Make sure you disconnect any unused ethernet ports.
Wireless Network Threats
Since wireless networks don’t require the user to be physically present to access it, they pose a lot of risks. They use radio waves to transmit data, and an intruder can use various techniques to intercept this data provided they are in the vicinity. From your company’s lobby or in the parking area, they can eavesdrop on your wireless communication. To protect against malicious actors who seek to exploit your wireless network, encrypt all data, filter MAC addresses, use a WPA password, and use a strong firewall.
Software Vulnerabilities
Before installing and using any business application, first, verify its source. Most tools are not always what they seem to be. Some contain dangerous codes that can be used to spy or steal sensitive information. Also, ensure all the tools you use are frequently updated. Outdated applications can be exploited by hackers to gain access to critical information.
Summary
With so many critical operations relying on the network, your company needs to take serious steps towards protecting your network infrastructure. To protect your assets, your customers and secure the future of your business, train your employees, secure your wired and wireless networks, and update your security measures regularly.
