Community safety refers to all of the practices and software program utilized by companies to guard the integrity, confidentiality and accessibility of their digital property. It ensures that your information stays protected against totally different safety threats comparable to malware and information breaches.
Groups using the appropriate community safety measures can count on uninterrupted companies whereas stopping unauthorized entry and knowledge theft.
Given the evolving and numerous nature of cyber assaults, manufacturers have to make use of totally different sorts of protecting measures to avoid wasting themselves from such vulnerabilities.
On this article, we’ll have a look at 5 sorts of community safety measures and perceive how they’ll safeguard your group’s digital infrastructure.
1. Firewalls
Firewalls are like safety guards on your community visitors. They have a look at the incoming and outgoing visitors out of your programs and monitor them primarily based on a set of predefined guidelines. If a request appears to originate from an untrusted supply, a firewall prevents it from going by way of.
They examine every information packet that enters or exits the community by its supply and vacation spot deal with, port, and protocol. This ensures that solely official requests are processed and accepted.
Fashionable sorts of firewalls embody:
- Packet-filtering firewalls: Study the packet primarily based on easy guidelines however don’t think about context.
- Stateful inspection firewalls: Monitor energetic connections and make choices primarily based on the well being of that connection.
- Hybrid mesh firewalls: Combines a number of firewall sorts to safe your community. A hybrid mesh firewall is normally leveraged in advanced and distributed environments.
- Proxy firewalls: Act as intermediaries between the tip consumer and the community. It inspects the visitors on the software degree.

2. Intrusion prevention programs
An Intrusion Prevention System (IPS) continuously screens the community visitors, identifies suspicious visitors, and takes rapid motion to dam or mitigate dangers. In contrast to intrusion detection programs (IDS), which alert admins about potential threats, IPS takes proactive motion.
It makes use of signature-based detection to establish recognized assault patterns and anomaly-based detection to identify uncommon or suspicious actions. As soon as a menace is recognized, the IPS can take varied actions, comparable to blocking visitors from the supply and resetting a community connection.
IPSs are efficient at stopping a variety of threats:
- Malware: Stops the unfold of malicious applications like viruses and worms.
- Denial of Service (DoS) assaults: Prevents threats that purpose to overwhelm and disable community assets.
- Exploits: Blocks try to benefit from present vulnerabilities in programs and purposes.
- Brute power assaults: Detects repeated failed login makes an attempt and halts unauthorized entry efforts.
3. Knowledge loss prevention
Knowledge Loss Prevention (DLP) prevents delicate organizational information from being misplaced, leaked, or accessed by unauthorized customers. Firms want it to shield confidential info, adjust to laws, keep away from monetary penalties, and keep their fame.
It secures information each in transit and at relaxation, guaranteeing the info stays safe always.
DLP options safe networks by monitoring and controlling information move throughout networks, endpoints, and cloud environments. Every serves distinct functions:
- Community DLP: Screens information in movement throughout the community and prevents unauthorized sharing of delicate info.
- Endpoint DLP: Protects information on particular person gadgets comparable to laptops, workstations, and smartphones by controlling file transfers and exterior storage utilization.
- Cloud DLP: Secures delicate information on distant servers and cloud purposes, guaranteeing each safety and compliance.
They examine the content material and context to acknowledge protected information and apply pre-defined guidelines to cease violations.
When a breach is detected, a typical DLP system can take many actions together with encrypting the info, blocking file switch, or alerting the directors.

4. Community entry management
The Community Entry Management (NAC), because the identify suggests, regulates the place the info or purposes may be reached. It ensures that solely approved customers can entry the organizational information on compliant gadgets.
This community safety measure prevents the connection of an unapproved machine to make sure the safety and security of personal information.
Directors will first have to grant entry to customers and authorize their gadgets. When the consumer makes an attempt to attach with the community, the NAC will confirm the credentials. If handed, the consumer can entry the related information.
On the flip facet, if the credentials don’t match, the NAC can block, quarantine, or restrict the consumer’s entry to the info. The admins can set guidelines for this primarily based on their organizational wants.
NAC options typically use applied sciences like role-based entry management, endpoint safety assessments, and multi-factor authentication to strengthen safety. These applied sciences improve safety, keep compliance, and enhance productiveness (by way of automation).
5. Community segmentation
Community segmentation is the method of breaking a community into small items. Within the occasion of a breach or information corruption, every of those items may very well be remoted to include the injury.
Furthermore, this additionally improves the efficiency of every of the subnetworks, guaranteeing the operations proceed as ordinary.
Safety groups can create boundaries between totally different elements of the community to create these community segments. The three common methods to do this embody:
- Bodily segmentation: Use separate bodily gadgets, like switches and routers, to create boundaries to separate networks.Â
- Logical segmentation: Create separate community segments utilizing software program referred to as digital LANs (VLANs). This improves effectivity and reduces price as you may handle a number of remoted networks on a single infrastructure.
- Micro-segmentation: The separation occurs on the software or workload degree. It’s performed by isolating the visitors between particular person gadgets or companies. Specialised software-defined networking (SDN) to implement safety insurance policies.

Wrapping up
The state of cybersecurity in 2024 requires organizations to make use of multi-layered community safety measures to sort out the wide range of digital threats.
Firewalls are the primary line of protection that filters the visitors and blocks unauthorized entry. IPS actively screens the community exercise throughout operation to detect and cease assaults. DLP screens and prevents the unauthorized sharing of delicate info by limiting entry instantly.
NAC solely ensures that approved customers from compliant gadgets can entry organizational info. Lastly, community segmentation breaks the community into smaller segments, permitting the admins to restrict the unfold of assaults or corrupt personal information.
All the safety measures work collectively to assist companies and enterprises shield their and their prospects’ information. Organizations can leverage them to attenuate vulnerabilities and safeguard their worthwhile info.
