On the first day of the week we held a meeting with Gül
Ayd?n,who is the head of the test and evaluation department.We introduced our
projects and they were informed about them.Immediately after the meeting I
interviewed my manager and got information about the last missing parts.After
these meetings I went to work to make the final touches of the project.I
concentrated on hardware and software firewalls. I solved their structures
and comparisons.The closure of missing parts and the achievements of this
week can be summarized as follows;
-Hardware firewall, the total cost is easily calculated at
first. There are device and update prices. In the case of software firewalls,
the cost of hardware, operating system, database, and backup should also be
taken into consideration while the cost is being calculated.
-Hardware Firewall has high performance because it is specially
designed. Software firewall performance depends on many parameters.
-Hardware Firewall, security is very high because it is custom
designed. Only certain ports are open. In software firewalls, security
vulnerabilities arise from operating system and other applications.
-Hardware Firewall is easy to install. In general, operations
can be done through a single interface.
-Hardware Firewall, updating is easy. A single firmware is
installed. Software firewalls are also hard to update. All applications need
to be updated separately.
-Hardware Firewall is generally not upgradeable. Software
firewalls can also be upgraded with hardware limits. (Processor, RAM, disk,
Hardware firewalls are systems that run by being integrated into
the router between a server and the network. The ability to manage traffic
and distinguish which server is appropriate for which filtering rules makes
it the ideal choice for systems with multiple servers.The most important
advantages of hardware firewall are speed and security.Hardware firewalls can
handle more traffic volume than they are designed for faster response
times.Also these firewalls with its own operating system is less prone to
attack. This reduces security risks.
Software firewalls are installed on individual servers and
disconnect each connection request to determine if the request is valid.
Despite their disadvantages in terms of performance, they also have many
advantages. Some of these important advantages are;
-Ease of use
-Full control of traffic.
