How to Protect Your Server from Hackers

How to Protect Your Server from Hackers
2
Computer dedicated servers store all the valuable
data you need to run a system, whether for its
business, academic, communication or many other
fields. Thats why it should be the most
protected part of any computer system. If your
system is fairly new, you can protect your server
from its most notorious predatorshackers.

Firewalls
A firewall is a piece of software (or hardware)
that controls what services are exposed to the
network. This means blocking or restricting
access to every port except for those that should
be publicly available. On a typical server, a
number services may be running by default. These
can be categorized into the following groups
4
Public services that can be accessed by anyone on
the internet, often anonymously. A good example
of this is a web server that might allow access
to your site.Private services that should only be
accessed by a select group of authorized accounts
or from certain locations. An example of this may
be a database control panel.Internal services
that should be accessible only from within the
server itself, without exposing the service to
the outside world. For example, this may be a
database that only accepts local
connections.Firewalls can ensure that access to
your software is restricted according to the
categories above. Public services can be left
open and available to everyone and private
services can be restricted based on different
criteria. Internal services can be made
completely inaccessible to the outside world. For
ports that are not being used, access is blocked
entirely in most configurations.

Protect your codes.
When creating your program codes for applications
that your intended end users interacts with, make
sure that appropriate error trappings are placed
within the application. Hackers typically use SQL
injections, or the manipulation of an
applications code through its URL or SQL
forms. When your program lacks error trappings
that can cover loopholes where SQL queries can be
injected, your server becomes a sitting duck to
hackers.

Public Key Infrastructure and SSL/TLS Encryption
Public key infrastructure, or PKI, refers to a
system that is designed to create, manage, and
validate certificates for identifying individuals
and encrypting communication. SSL or TLS
certificates can be used to authenticate
different entities to one another. After
authentication, they can also be used to
established encrypted communication. Limit
uploads. Your server will need to accept data
from end users in order for it to gather
information. Though uploads are necessary, you
still need to limit the amount of information
going in to the system.
7
To do this, format forms properly to make sure
that only the required data gets into the
system.Use passwords. Passwords are the most
basic tool you can use and your first line of
defense in protecting your server from hackers.
Using passwords restricts any unauthorized access
to your system those without extensive technical
know-how will find it hard to get into your
system. Make sure that the password you make are
complex and very hard to crack. Using
combinations of special characters, mixed cases
and numbers will make it harder to break.How Do
They Enhance Security? Isolating your processes
into individual execution environments increases
your ability to isolate any security problems
that may arise. Similar to how bulkheads and
compartments can help contain hull breaches in
ships, separating your individual components can
limit the access that an intruder has to other
pieces of your infrastructure.
8
How Difficult Is This to Implement?
Depending on the type of containment you choose,
isolating your applications can be relatively
simple. By packaging your individual components
in containers, you can quickly achieve some
measure of isolation, but note that Docker does
not consider its containerization a security
feature. Setting up a chroot environment for each
piece can provide some level of isolation as
well, but this also is not foolproof method of
isolation as there are often ways of breaking out
of a chrootenvironment. Moving components to
dedicated machines is the best level of
isolation, and in many cases may be the easiest,
but may cost more for the additional machines.

Conclusion
The strategies outlined above are only some of
the enhancements you can make to improve the
security of your systems. It is important to
recognize that, while its better late than
never, security measures decrease in their
effectiveness the longer you wait to implement
them. Security cannot be an afterthought and must
be implemented from the start alongside the
services and applications you are providing.
