The objective of network
security assessment services is to keep data assets secure and protect the
enterprise IT infrastructure. Typically, businesses are threatened by
technology risks and vulnerabilities for being connected to internet or for
handling confidential client information. There are statistical evidences about
network security supported by enterprise network security company, which states
that in countries such as Mexico, Brazil, United States, Colombia, Argentina,
UAE, India; two out of three companies suffer attacks on their IT networks.
Many
companies believe that by simply installing an antivirus or firewall in their
networks, they are free of risks. This is a very common error as there are
risks associated with these, but there are many other risks which can’t be
fixed by only antivirus or firewall. To preserve enterprise network security,
they must consider all types of IT risks. IT risks can be classified into
external risks and internal risks. External risks originate outside the company’s
network such as an external network hacker. Internal risks originate within the
network such as an employee or an external hacker who has access to network
resources.
According
to enterprise network security training course professor, many risks arise due to inefficient
network security solutions that companies have and because of lack of knowledge
related to the implementation of enterprise network security solutions. Network
security solutions protect enterprise networks and resources from external and
internal risks. As per case studies from an enterprise network security
company, network security is the key for meeting the data protection standards
and gain customer trust. Below are some of the ways for improving Ethernet and
wireless security.
WAYS TO IMPROVE ETHERNET NETWORK SECURITY
If you
are configuring a computer network, you can follow some of the below mentioned
security mechanisms recommended by enterprise network security company.
§ As per
enterprise network security training course; to increase security in the
network, you should enable automatic software updates for each computer and
network device. Normally firmware and operating systems automatically install
important updates. An update may include patches for some vulnerabilities or an
upgrade to improve the user experience and performance.
§ Use a
firewall that could prevent hackers from gaining access to network resources. A
firewall provides access control and filters all network communications.
Implementing other enterprise network security solutions along with firewalls
can isolate networks to prevent certain types of data flow. According to
enterprise network security company consultants; some firewall can allow access
to the local network from the Internet if the user has logged in as an internal
user. Some firewalls also have Anti-Spam functionality or you must use a
separate Anti-Spam solution in the network.
§ Virus
can get into your computer for spam, hard disk, USB, CDs or files downloaded
from Internet. As there are new kinds of viruses every other day, antivirus
software must be updated periodically. Antivirus help detect and sometimes in
the removing virus. According to the experience of enterprise network security
company consultants; there are different types of antivirus solutions in the
market. Consultants of enterprise network security solutions suggest that
general users can use free antivirus like Avast but enterprise users should use
appropriate solution depending on the type of infrastructure.
§ Use
IDS- IPS (intrusion detection system and intrusion prevention system). IDS, IPS
are network security services that enable intrusion detection and intrusion
prevention. An IDS / IPS proactively detects complex traffic patterns and gives
an ability to respond to any imminent attack on your network. According to
enterprise network security services experts, intrusion detection and intrusion
prevention system is a software / hardware used to detect cyber attacks over a
computer or a network. The events generated by IDS / IPS should be supervised
by your company’s team or company can take the help of enterprise network
security company which can analyze network traffic in real time with the help
of network security
assessment services.
§ VLAN
(Virtual LAN) is a method of creating independent logical networks within a
computer network. A computer network can have multiple virtual networks. VLAN
is one of the important enterprise network security solutions that divide
groups of network users in a real physical network into logical segmented
networks. Enterprise network security training course professor explains that
VLAN network is a network of computers that behave as if they were connected to
the same switch. You can configure VLANs through software rather than hardware,
which makes them considerably flexible. To deploy more security, you can learn
how to configure Private VLAN, VLAN Micro with the help of network security
training course.
§ An
access control list or ACL used to implement logical security. ACL is one of
the enterprise network security solutions that can help determine the
appropriate access permissions for a network resource. ACL filters network
traffic and only allows network traffic based on some condition. ACL can also
be used to filter out traffic flow in computers, routers and network switches.
According to network security assessment services specialists; the access
control list is a basic necessity for any network. You must set rules detailing
service ports, domain names, and terminal names along with the ACL permissions.
A combination of VLAN and ACL is very good for security and you can easily
learn how to configure VLAN ACL’s with the help of network security course.
§ Implement
network security solutions such as IPsec (Internet Protocol Security) for
encryption. IPsec is a set of protocols used for secure communications at the
network layer and the transport layer, both TCP and UDP. IPsec helps in
authentication and encryption of data packets. According to network security
assessment services experts, IPsec is very flexible because it can be used to
protect Internet Protocol (IP) and Transport protocol (TCP, UDP). You can use
IPsec with applications that use SSL or TLS. You can also use VPN for critical
communications or implement a complete IPsec solution.
§ Install
RADIUS, TFTP servers depending on the business requirements along with other
enterprise network security services & solutions mentioned before.
§ Enable
logs server, which will enable you to record all activity on the network.
According to enterprise network security training course professor; this part
is very important for tracking all the hacking incidents.
§ Audit
configurations of network devices and select a configuration knowing its
purpose. You must also change the default settings and configurations of
switch, router and other network devices. For network application security,
network security services expert advice that you should disable any unused
services. Thus you should check the running services related to all network
devices & applications and disable or uninstall the service that you are
not using.
§ You can
also take help of enterprise network security company or provider to implement security,
backup policies and to do network security audit with intrusion detection and
vulnerabilities testing.
WAYS TO IMPROVE WIRELESS NETWORK
SECURITY
If you
are configuring a wireless network, you can follow some of the below mentioned
security mechanisms recommended by enterprise network security company.
§ You
must configure a security key of wireless network with Wi-Fi Protected Access 2
(WPA2-PSK) enabled. With encryption enabled, no one can connect to your network
without the security key and is very difficult to do brute force. This would
help prevent attempts of unauthorized access to the network and communications.
You must choose a very strong security key so that dictionary attacks cannot
crack the password.
§ You
must change the name and default administrator password on your router or
access point. In addition you should change default wireless network name known
as default network identifier (SSID). You can also use various wireless network
security solutions that will change the keys, passwords and SSID periodically.
§ You
must select the location of the router or access point carefully so that the
signal does not reach outside your facilities.
§ You can
filter MAC addresses and allow WiFi access to known devices. There is also an
option to hide SSID so that it is not visible in regular search of available
networks.
These
network security solutions are basic for any kind of security implementation for
wired and wireless network. For more secure networks, you should take help of
an enterprise network security company. If you have question “how to learn
network security”, you can take our enterprise network security training course
