The quality or state of being secure to be free from danger Security is achieved using several strategies simultaneously or used in combination with one another Security is recognized as essential to protect vital processes and the systems that provide those processes Security is not something you buy, it is something you do What is security?
- 7. Vulnerability, Threat and Attack A vulnerability:- is a weakness in security system Can be in design, implementation, etc. Can be hardware, or software A threat:- is a set of circumstances that has the potential to cause loss or harm Or it’s a potential violation of security Threat can be: Accidental (natural disasters, human error, …) Malicious (attackers, insider fraud, …) An attack:- is the actual violation of security
- 8. Why Systems are Vulnerable? Hardware problems- • Breakdowns, configuration errors, damage from improper use or crime Software problems- • Programming errors, installation errors, unauthorized changes) Disasters- • Power failures, flood, fires, etc. Use of networks and computers outside of firm’s control - • E.g. with domestic or offshore outsourcing vendors
- 9. SO HOW DO WE OVERCOME THESE PROBLEMS???
- 10. BUSINESS VALUE OF SECURITY AND CONTROL • Inadequate security and control may create serious legal liability. • Businesses must protect not only their own information assets but also those of customers, employees, and business partners. Failure to do so can lead to costly litigation for data exposure or theft. • A sound security and control framework that protects business information assets can thus produce a high return on investment.
- 11. ESTABLISHING A MANAGEMENT FRAMEWORK FOR SECURITY AND CONTROL General controls: Establish framework for controlling design, security, and use of computer programs • Software controls • Hardware controls • Computer operations controls • Data security controls • Implementation controls
- 12. ESTABLISHING A MANAGEMENT FRAMEWORK FOR SECURITY AND CONTROL Application controls: • Input • Processing • Output Unique to each computerized application
- 13. CREATING A CONTROL ENVIRONMENT Controls:- • Methods, policies, and procedures • Ensures protection of organization’s assets • Ensures accuracy and reliability of records, and operational adherence to management standards
- 14. Worldwide Damage from Digital Attacks
- 15. CREATING A CONTROL ENVIRONMENT Disaster recovery plan: Runs business in event of computer outage Load balancing: Distributes large number of requests for access among multiple servers
- 16. CREATING A CONTROL ENVIRONMENT • Mirroring: Duplicating all processes and transactions of server on backup server to prevent any interruption • Clustering: Linking two computers together so that a second computer can act as a backup to the primary computer or speed up processing
- 17. CREATING A CONTROL ENVIRONMENT Internet Security Challenges Firewalls:- • Hardware and software controlling flow of incoming and outgoing network traffic • Prevent unauthorized users from accessing private networks • Two types: proxies and stateful inspection Intrusion Detection System:- • Monitors vulnerable points in network to detect and deter unauthorized intruders

- 20. Access Control - Physical USER RESPONSIBILITIES • Follow Security Procedures • Wear Identity Cards • Ask unauthorized visitor his credentials • Attend visitors in Reception and Conference Room only • Bring visitors in operations area without prior permission • Bring hazardous and combustible material in secure area • Practice “Piggybacking” • Bring and use pen drives, zip drives, ipods, other storage devices unless and otherwise authorized to do so
- 21. Password Guidelines Always use at least 8 character password with combination of alphabets, numbers and special characters (*, %, @, #, $, ^) Use passwords that can be easily remembered by you Change password regularly as per policy Use password that is significantly different from earlier passwords Use passwords which reveals your personal information or words found in dictionary Write down or Store passwords Share passwords over phone or Email Use passwords which do not match above complexity criteria
- 22. Dictionary Attack Hacker tries all words in dictionary to crack password 70% of the people use dictionary words as passwords Brute Force Attack Try all permutations of the letters & symbols in the alphabet Hybrid Attack Words from dictionary and their variations used in attack Shoulder Surfing Hackers slyly watch over peoples shoulders to steal passwords Dumpster Diving People dump their trash papers in garbage which may contain information to crack passwords Password Attacks - Types
- 23. Internet Usage Use internet services for business purposes only Do not access internet through dial-up connectivity Do not use internet for accessing auction sites Do not use internet for hacking other computer systems Do not use internet to download / upload commercial software / copyrighted material Technology Department is continuously monitoring Internet Usage. Any illegal use of internet and other assets shall call for Disciplinary Action.
- 24. CREATING A CONTROL ENVIRONMENT Antivirus Software Antivirus software: - Software that checks computer systems and drives for the presence of computer viruses and can eliminate the virus from the infected area • Wi-Fi Protected Access specification

- 26. MANAGEMENT CHALLENGES Implementing an effective security policy Applying quality assurance standards in large systems projects What are the most important software quality assurance techniques? Why are auditing information systems and safeguarding data quality so important?
- 27.
