26. Software Security

27. What is a Software?
• Software, in simple words, is a collection
of instructions that enable the user to interact
with a computer, its hardware, or perform tasks.
Without software, computers would be useless.
• Examples are AVG, Windows 7, Outlook, Computer
drivers etc.

28. Types of Software
• There are two main types of software:-
1)Application software:
Application software are often called productivity
programs or end-user programs because they
enable the user to complete tasks such as
creating documents, spreadsheets, databases,
and publications, doing online research, sending
email, designing graphics etc.
Examples are Microsoft Excel, Outlook, Skype etc.

29. 2) System Software:
Systems software includes the programs that are
dedicated to managing the computer itself,
such as the operating system, file management
utilities, and disk operating system (or
DOS). Without systems software installed in
our computers we would have to type the
instructions for everything we wanted the
computer to do!
Examples are Microsoft Windows, Mac OS X,
LINUX etc.

30. Software Security
• Software security:-
Software security is an idea implemented to protect
software against malicious attack and other
hacker risks so that the software continues to
function correctly under such potential risks.
Security is necessary to provide integrity,
authentication and availability.

31. • Why do we need software
security?
Any compromise to integrity, authentication and
availability makes a software unsecure. Software
systems can be attacked to steal information,
monitor content, introduce vulnerabilities and
damage the behavior of software. Malware can cause
DoS (denial of service) or crash the system itself.
Buffer overflow, stack overflow, command injection
and SQL injections are the most common attacks on
the software

32. • Command injection can be achieved on the
software code when system commands are used
predominantly. New system commands are
appended to existing commands by the malicious
attack.
• The only way to avoid such attacks is to practice
good programming techniques. System-level
security can be provided using better firewalls.
Using intrusion detection and prevention can also
aid in stopping attackers from easy access to the
system.

33. Pros and cons of
software security
• Advantages:
The advantages of software security are as
follows:-
1) Protects system against viruses, worms,
spyware and other unwanted programs.
2) Protection against data from theft.
3) Protects the computer from being hacked.
4) Minimizes computer freezing and crashes.
5) Gives privacy to users.

34. • Disadvantages:
Following are the disadvantages of software
security:-
1)Firewalls can be difficult to configure correctly.
2) Incorrectly configured firewalls may block
users from performing certain actions on the
Internet, until the firewall configured correctly.
3) Makes the system slower than before.
4) Need to keep updating the new software in
order to keep security up to date.
5) Could be costly for average user.
