Enterprise Firewalls Feature and Benefits

Enterprise Firewalls

• The Network Enterprise Firewalls are defined as
  standalone purpose-built firewall appliances with
  IPSec VPN capabilities, capable of delivering
  extensive firewall and management capabilities
  for securing the perimeter access. Enterprise
  firewalls incorporate also IPS technologies,
  replacing perimeter IPS as well.
• Further integration with more application and
  user awareness protection capabilities are also
  emerging on these firewalls. This combination is
  known as Next-Generation Firewalls.

How Firewall Protects Enterprises

• Firewall protects networks from potential
  security threats which attempt to infringe into
  the network protocol to gain access to remote
  PCs. It provides access to only specific data
  over enterprise network and restricts any other
  unknown source from getting access to the data.

Types of Enterprise Firewall

• Firewalls have been taking care of network
  security since 1980s. Back then, they were
  simple packet filter systems that check the
  header of the incoming data for its details and
  accepted or rejected it based on the protocol.
• Firewalls are categorized based on the network
  they are protecting, interception point and the
  data form that is being intercepted. Currently,
  there are three types that cover almost all kinds
  of network security threats.
• Network Layer Firewall or Packet Filters
  Network layer firewalls work on the network and
  filter data based on the packets they arrive in.
  They can be both state full and stateless based
  on the fact whether they maintain or dont
  maintain a state table of the network activity.

Types of Enterprise Firewall (Cont.)

• Application Layer Firewall Application firewalls
  work on the application layer stack of TCP/IP.
  Thus, they can be set to inspect data flow from a
  particular application and scrutinize the traffic
  for any threats. This is an efficient option for
  enterprise security, with the only constraint
  being that application level checking ads to data
  transfer time.
• Proxy Firewall Proxy Firewalls use proxy
  servers as gateways between networks. These can
  be either hardware or software and are considered
  to be the most efficient firewall systems.
  Existence of a proxy server between an external
  and internal network makes tampering difficult.
  The system is so compound that even if one
  application is hacked, it is almost impossible to
  use simple hack codes to reach other internal
  application through it.

Benefits of Enterprise Firewalls

• Linear Performance and Scalability
• Chassis with blade systems offers linear
  performance and scalability on demand, as more
  blades are added to the chassis.
• Chassis architecture offer also the possibility
  to add supplemental functionalities to NGFW (next
  generation firewalls), like IPS, web applications
  security, antivirus, antispam etc, with no
  performance degradation.

Benefits of Enterprise Firewalls (Cont.)

• Deployment Advantages
• Single point of control at the edge / perimeter
  for access.
• Application and user awareness for both inbound
  and outbound traffic.
• IPSec VPN consolidation of all branch
  communication.
• Physical separation of the DMZ, trust and untrust
  zones.
• Virtualization
• Device virtualization (multi-tenancy, virtual
  systems, security contexts) for independent
  operation with individual security needs for
  different business divisions.
• Separate administrators for each virtual system
  can tailor security and access policies for each
  group, thus offering a more granular level of
  control and security.

Enterprise Security Tips Come in Handy in order
to Protect the Digital Interests of Small
Businesses

• Be prepared A common mistake that businesses
  make is not deploying significant security
  measures. The truth is that attackers launch a
  widespread attack and anyone may fall prey to it.
  Expecting the unexpected is half the battle won.
  This makes it all the more important to stay
  prepared for any kind of security threats that
  you may face.
• Monitor Employees Your employees may be loyal
  and may not deliberately sabotage your networks
  security but even with the best of intentions,
  they might still (somehow) wind up clicking on a
  link which compromise with the security of your
  network. It is advisable to block access to
  questionable sites and keep a track the
  activities of your employees.
• Use Centralized Visibility Centralized
  visibility grants more authority to the right
  people, such as the IT team, the owners of the
  company and others who are intricately related to
  certain or all managerial aspects. You may
  leverage centralized visibility across your
  network by resorting to specific hardware tools
  that come with such capabilities.

• Keep all security related software running
  There are obviously quite a few systems in every
  network that are handled by several people.
  However, everyone doesnt have the patience to go
  through notifications related to anti-virus,
  malware, spyware and firewall warnings. Its
  sensible to limit the accessibility rights of all
  such software to the IT department, so they
  always remain functional.
• Secured File Sharing File sharing is one of the
  more prominent ways through which viruses and
  malware spread. Companies with sophisticated
  networks use file encryption to ensure their
  networks remain sophisticated. In addition to
  reducing chances of viral encroachments, secured
  file sharing also reduces the possibility of
  accidently sending files to a wrong recipient.
  Another benefit of secured file sharing is that
  you can track your files after sending them and
  authenticate users that can or cant view them.

Advantages of Enterprise Firewall

• Enterprise firewall may be customized as per the
  business requirement.
• There is no limit to the type of firewall that
  may be configured.
• Within an enterprise network, firewall may be
  programmed in a manner that prevents access to
  certain websites.
• Firewall may be easily configured to prevent
  employees from transmitting confidential data
  outside the enterprise network.
• Connecting computers to the internet exposes them
  to numerous security risks, but having a firewall
  protection in place may effectively eliminate
  these risks. However, in order to achieve desired
  output, it is important to purchase a next
  generation firewall from a credible source. Make
  sure that you read online reviews before you
  invest in any firewall software.

Disadvantages of Enterprise Firewall

• Legitimate User Restriction
• Diminished Performance
• Vulnerabilities
• Internal Attack
