Every business has a responsibility to secure data and sensitive customer details.
Senior Management and IT are responsible for Network Security to prevent data breaches from cyber criminals, hackers and identity thieves
- Protection for the network includes network firewalls, intrusion prevention and application control.
- Protection for the system against viruses, Trojan-horse and spam software needs endpoint security software and encryption technology.
Implementing a layered network security strategy requires a great deal more than buying an off-the-shelf security product.
To ensure total security you need an integrated solution that has been designed and implemented by professionals who understand the ever-evolving threats your organisation is now facing.
Board Management (including IT) should be responsible for:
- IT security policies that preserve the confidentiality, integrity, and availability of systems and information used by the business.
It is therefore essential not only to have a good network security system with the right technology in place but also to have the right security policies and training, which helps employees to keep security awareness in mind at all times.
Other Types of Network Security
Not every user should have access to your network. To keep out potential attackers, you need to recognise each user and each device. Then you can enforce your security policies. You can block non-compliant endpoint devices or give them only limited access. This process is called network access control (NAC).
Antivirus and anti-malware software
"Malware," short for "malicious software," includes viruses, worms, Trojans, ransomware, and spyware. Sometimes malware will infect a network but lie dormant for days or even weeks. The best anti-malware programs not only scan for malware upon entry, but also continuously track files afterward to find anomalies, remove malware, and fix damage.
Any software you use to run your business needs to be protected, whether your IT staff builds it or whether you buy it. Unfortunately, any application may contain holes, or vulnerabilities, that attackers can use to infiltrate your network. Application security encompasses the hardware, software, and processes you use to close those holes.
To detect abnormal network behavior, you must know what normal behavior looks like. Behavioral analytics tools automatically discern activities that deviate from the norm. You can then better identify indicators of compromise that pose a potential problem and quickly remediate threats.
Data loss prevention
Organisations must make sure that staff do not send sensitive information outside the network. Data loss prevention, (or DLP) can stop people from uploading, forwarding, or even printing critical information in an unsafe manner.
Email gateways are the number one threat vector for a security breach. Attackers use personal information and social engineering tactics to build sophisticated phishing campaigns to deceive recipients and send them to sites serving up malware. An email security solution can block incoming attacks and controls outbound messages to prevent the loss of sensitive data.
Intrusion prevention systems
An intrusion prevention system (IPS) scans network traffic to actively block attacks. Next-Generation appliances do this by correlating huge amounts of global threat intelligence to not only block malicious activity but also track the progression of suspect files and malware across the network to prevent the spread of outbreaks and reinfection.
Mobile device security
Cybercriminals are increasingly targeting mobile devices and apps. Within the next 3 years, 90 percent of IT organisations may support corporate applications on personal mobile devices. Of course, you need to control which devices can access your network. You will also need to configure their connections to keep network traffic private.
Software-defined segmentation puts network traffic into different classifications and makes enforcing security policies easier. Ideally, the classifications are based on endpoint identity, not mere IP addresses. You can assign access rights based on role, location, and moren so that the right level of access is given to the right people and suspicious devices are contained and remediated.
Security information and event management
SIEM products pull together the information that your security staff needs to identify and respond to threats. These products come in various forms, including physical and virtual appliances and server software.
A virtual private network encrypts the connection from an endpoint to a network, often over the Internet. Typically, a remote-access VPN uses IPsec or Secure Sockets Layer to authenticate the communication between device and network.
A web security solution will control your staff’s web use, block web-based threats, and deny access to malicious websites. It will protect your web gateway on site or in the cloud. "Web security" also refers to the steps you take to protect your own website.
Wireless networks are not as secure as wired ones. Without stringent security measures, installing a wireless LAN can be like putting Ethernet ports everywhere, including the parking lot. To prevent an exploit from taking hold, you need products specifically designed to protect a wireless network.
