The way businesses protect their computer networks has changed. Now, every device connected to the network—like computers, phones, servers, and smart gadgets—is a crucial point of defense. This means that each device can be a weak spot if not properly secured.
If you don’t use the same security rules for all devices, you’re creating an easy target for cyberattacks.
That’s why it’s so important to have a complete plan for securing all devices. This plan should focus on seeing all devices on the network, finding threats quickly, and using a “Zero Trust” approach.
The Endpoint: A Common Target for Attacks
Cybercriminals know that a company’s security is only as strong as its weakest point. Often, this weak point is one of its endpoints, the computers that team members use to work, store company information, and connect to the network.
- Human Error: Your team members are just people interacting with their computers, making them vulnerable to tricks like phishing (fake emails designed to steal information) and targeted attacks on specific software. If one person’s computer is successfully attacked, it gives criminals a way to get into the network and find more weaknesses.
- Stealing Data and Passwords: Devices often hold or can access important company information. If a device is compromised, it can directly lead to the theft of company secrets, private personal details, and network passwords, allowing attackers to go deeper into the system.
- Moving Around the Network: Once a device is compromised, it can quickly be used as a starting point for attackers. They use this access to learn about the internal network, look for weaknesses on other computers, and spread to valuable targets like main servers and data storage areas.
Fighting Advanced and Persistent Threats
Today’s cyber threats are not just simple viruses. They are often “Advanced Persistent Threats” (APTs), which are carried out by highly skilled and focused attackers. These attacks are hard to detect, last a long time, and are custom-made for each target.
APT groups thoroughly gather information about a company’s computer systems and employees. They create special tools to exploit weaknesses and use normal system tools to hide their activities, making them very difficult to find once they are inside the network.
Key Parts of a Modern Device Security System
Protecting the outer edge of your network is necessary, but it’s not enough for today’s businesses. A strong security plan must treat every device as a potential threat and constantly check its security. Here are a couple of proven strategies:
Zero-Trust Architecture
The “Zero Trust” security model is the current standard. It replaces the idea of automatically trusting devices with continuous, clear checks.
Never Trust, Always Verify
Every request to access the network—from any user, on any device, whether inside or outside the company—must be checked, approved, and continuously verified against set rules before access to only necessary resources is granted.
Containment
When a Zero Trust policy is correctly put in place, if a single device is compromised, the attack can be effectively stopped. This greatly limits the attacker’s ability to move around the network and gain more control.
Endpoint Detection and Response (EDR)
Old-fashioned antivirus software is no longer enough. The modern requirement is Endpoint Detection and Response (EDR).
Behavioral Analysis and AI
EDR solutions provide a clear view of all device activity in real-time. They continuously monitor and analyze what’s happening on each device. They use machine learning and behavioral analysis to spot unusual patterns and changes from normal activity. This helps them catch advanced threats like fileless malware and attacks that use legitimate system tools, which traditional antivirus software would miss.
Incident Response Capability
EDR is crucial for security teams. It provides detailed information for investigations and tools to fix problems remotely, which are necessary to quickly find and stop confirmed threats.
Strict Cyber Hygiene
Attackers often take advantage of known weaknesses that come from poor security practices.
Vulnerability and Patch Management
A proactive and automated system for managing software updates is essential. Security updates for operating systems and other applications must be installed immediately when they are released to fix publicly known weaknesses.
Secure Configuration Baseline
Every device must follow a secure basic setup. This includes turning off unnecessary services, removing default or easily guessed passwords, and strictly making sure that all users and applications only have the minimum access they need.
Being able to see and control all devices is extremely important for keeping your valuable business information confidential and available. If you’re worried about your current network security, contact the IT experts at Fusion IT today at (616) 828-5360.
