Computer Engineering

1. In the real world, it is not an easy task to find a solution of a given problem because many constraints and limitations must be taken into account during this process.

2. It is expected that future experiments and field observations will be able to prove whether fish school movement can be described in such a way.

3. Since the method was applicable only to intuitionistic proofs, I had to find a method applicable to classical proofs.

4. When you close a map using this command, the map still exists on the server and can be modified at any time by reopening the map in the Map Author.

5. When a row is deleted, all of its attribute’s values are deleted and need not be individually specified.

6. For example, only system maintenance personnel may be authorized to modify system libraries, but many if not all other users may be authorized to execute programs from those libraries.

7. This person may be able to simulate the appearance of a totally separate, misleadingly labeled file following the counterfeit page.

8. The complex structure of the design process will have to be reflected in the structure of CAD system, if such systems are to support the design as a whole and not only isolated parts of it.

9. Both the designer of a CAD system and its potential user must be able to agree on a description of the interfaces of the computer-aided part of the design process with the remaining part of the process.

10. It can be thought of as partitioning: a single physical server is sliced into multiple small partitions (otherwise called virtual environments (VE), virtual private servers (VPS), guests, zones, etc.).

11. The computer analysis program can be best used to ensure virtually unconditional stability.

12. The expert system should be able to explain its reasoning and answer questions about the solution process.

13. The expert system won’t be able to prove or disprove something from the data initially supplied by the user, so it will ask the user some questions.

14. For point-to-point SMS, a message can be sent to another subscriber to the service, and an acknowledgement of receipt is provided to the sender.

15. By inserting the SIM card into another GSM terminal, the user is able to receive calls at that terminal, make calls from that terminal, and receive other subscribed services.

16. It can be argued that in many applications a hierarchic structure is a good approximation to the natural structure in the data.

17. One advantage to this approach is that your applications can be easily upgraded if necessary.

18. Initially it may have been thought that the key need not be stored with the data at the hash address.

19. This method has the advantage that records need never be moved once they have been entered in the bump table.

20. There are ways of partitioning trees in such a way that the number of disk accesses during a tree search can be reduced.

Information Security

1. Data may be protected by such basic methods as looking up terminals and replicating data in other storage facilities.

2. Operating systems and programs may also incorporate built-in safeguards.

3. Common sense is the most appropriate tool that can be used to establish your security policy.

4. Assessing the threat of information disclosure depends on the type of information that could be compromised.

5. While no system with highly classified information should ever be directly connected to the Internet, systems with other types of sensitive information might be connected without undue hazard.

6. The threat of losing the services of a mission-critical system must be evaluated seriously before connecting such a system to the network.

7. The investment in physical security should be based on your realistic assessment of the threat.

8. A worm has to get into your system somehow, so the fewer places where it can try, the better.

9. Any reputable package should have an official site and official mirrors. Official releases should be accompanied by an announcement to a relevant mailing list or web site.

20. Distribution of responsibility and control to small groups can create an environment of small easily monitored networks composed of a known user community.

21. An executable file can’t be modified by a virus if the write mode isn’t set.

22. This enables a closed form solution to security that works well when only a single well-characterized property can be isolated as critical.

23. The designers and operators of systems should assume that security breaches are inevitable.

24. The private key is kept secret, while the public key may be widely distributed.

25. The keys are related mathematically, but the private key can't be practically derived from the public key.

26. A message encrypted with the public key can be decrypted only with the corresponding private key.

27. Full audit trails should be kept of system activity, so that when a security breach occurs, the mechanism and extent of the breach can be determined.

28. In low security operating environments, applications must be relied on to participate in their own protection.

29. There are 'best effort' secure coding practices that can be followed to make an application more resistant to malicious subversion.

30. If the plan describes a generic high level design (reference architecture) then the plan should be based on a threat analysis.

31. If a third party has sufficient access to the computer, legitimately or not, this may be used to lessen the user's privacy.

32. Courts have not yet had to decide whether advertisers can be held liable for spyware which displays their ads.

33. These have to be used in combination to make the encryption secure enough, that is to say, sufficiently difficult to crack.

34. Social engineering and direct computer access (physical) attacks can only be prevented by non-computer means, which can be difficult to enforce, relative to the sensitivity of the information.

35. The clients are then able to adapt their requirements based on the information received through the reports.

36. You can specify individual hosts or sublets that should be allowed into the network, and you can specify what type of traffic should be allowed into the network.

37. To define requirements for a defense is a delicate task, because for an attacker, the potential of Denial Of Service attacks often depends on gaining access to any host(s), which do not have to be associated with your network at all .

38. Therefore, auditing should start at kernel level, in form of detailed verification and ability to record all of the systems actions, independent from logs generated by applications themselves, because they can never fully be trusted.
