As incidents of data theft and hacking
attacks keep making the headlines across the business pages, companies are
becoming paranoid about securing their systems against myriad threats. While
network security is critical, hardening your database is a key step for protecting
your data repository. An important aspect of database security involves
securing it from both internal and external threats. It also involves looking
at issues like authorization, dealing with privileges and virus attacks. So if
you are looking to secure your SQL Server implementation then just follow the
tips given below.
Start with Physical Security
In a typical discussion on IT security,
physical security rarely comes into the picture as we seem to be more bothered about
network security, software vulnerabilities etc. However in case of a corporate
database, maintaining a physical security posture is essential. In case a
malicious individual, which can even be a dissatisfied employee, gains access
to a terminal with an administrator account, he can play havoc with your data
repository. Hence you need to ensure that central database administration
terminals should be located in rooms which can be accessed only with privileged
access cards.
Build a complete need based hierarchy of
Rights and Access Roles
Not all employees should have access to
your entire database and most department personnel should ideally only deal
with data belonging to their department only. Again “sysadmin” accounts should
be rare and clear thought should be applied before giving access to each user.
Ideally permissions from respective managers need to be approved before the
same are allocated.
Give a thought to System security
The SQL Sever database application
typically runs on a Windows Server OS and it is extremely critical that the OS
is properly patched and protected with a powerful antivirus application. In
case you are using a virtualization solution, appropriate security measures
need to be put in place.
Network Connectivity – Harden it against
threats
Use the SQL Configuration tool to change
the ports that are normally associated with network communications. Leaving
them open allows hackers to target known ports and compromise your system. If
specific database instance has critical data, you may choose to even block it
from broadcasting data.
Secure your SQL Server Database against
data loss
Now that you have a fairly good idea about
the how you can go about securing your database against a plethora of threats,
its time you eliminate the other major bugbear associated with a SQL Server
database – the chance of data loss due to a system crash. Well the best way to
get back your data after a crash involves the use of a
recover sql tool like
DataNumen SQL recovery which comes loaded with a state of the art recovery
engine. The application is capable of negotiating even the largest of SQL
backup files that you may have, irrespective of whether they are stored in a
flash drive or a DVD set. Last but not the least the recovery process is
completed in a remarkably quick span of time while maintaining complete data
integrity.
