Even if they are using more resources than a simple antivirus program, Security Suites provide multiple protection layers against malware.
The security landscape changes continuously and you have to be fully protected against the
most common attack vectors:
- infections through files carried on USB sticks, memory cards, mobile
hard drives, downloaded files
- network attacks (spoofing, DOS)
- vulnerabilities that get exploited in common software
- drive-by downloads
- identity and financial theft through phishing websites
- spam and phishing emails
There are definitely other components that influence the security of a computer or a network (like backup).
The most basic security solution has to be able to protect the computer in real time against all types of malicious software that get transmitted as files (most common malware). To cover all these attack vectors you either install multiple individual security solutions or use a security suite that has them integrated.
