WHAT ARE THE SECURITY VIOLATION CATEGORIES?
1. Breach of confidentiality: unauthorized reading of data.
2. Breach of integrity: unauthorized modification of data.
3. Breach of availability: unauthorized destruction of data.
4. Theft of service: unauthorized use of resources.
5. Denial of Service(DOS): Prevention of legitimate use.
WHAT ARE THE SECURITY VIOLATION METHODS?
1. Masquerading (authentication breach): pretending to be an authorized user.
2. Replay Attack: Replaying the same message or adding a modification to it.
3. Man-in-the-middle attack: intruder sits in data flow, masquerading as sender to receiver and vice versa.
4. Session hijacking: intercepting a session which is already on going to by-pass authentication.
5. Privilege escalation: A really Common attack, access of resources that a user is not supposed to have.
WHAT ARE THE OTHER VARIATIONS OF HYPERVISORS?
1. Paravirtualization: guest OS is modified to work with VMM.
2. Programming-environment virtualization: VMMS do not virtualize hardware which creates optimized virtual system (Used by Oracle Java and Microsoft.Net).
3. Emulators: Allows applications written for one hardware to run on different hardware environments.
4. Application Containment: Not virtualization but, provides features like it by segregating application making them more secure and manageable.
Oracle Solaris Zones, BSD Jails, IBM AIX WPARs.
• Much variation is due to breadth, depth, and importance of virtualization.
WHAT ARE THE STEPS OF LIVE MIGRATION?
1. VMM start connection with the target VMM.
2. Target created a new guest (by creating a new VCPU).
3. VMM sends read-only files to target VMM.
4. VMM sends read-write files to target VMM.
5. Repeat 4 unit done as not all read-write data can be sent (could be a dirty read).
6. If step 4 and 5 becomes very short then, VMM freezes guest, send remaining stuff.
7. Target starts running the freezed guest.
WHAT ARE THE REASONS FOR DISTRIBUTED SYSTEMS?
1. Resource sharing
Sharing files, information, printing.
Using remote GPUs.
2. Computation speedup
dsitribute processing needed to multicomputers.
Load balancing: moving jobs to more lightly-laoded sites.
3. Reliability: detect and recover failurs.
WHAT ARE THE WIDELY USED ARCHITECTURES?
1. Client-server model.
2. Cluster-based model.
WHAT ARE THE CHALLENGES?
1. Naming and transparency.
2. Remote file access.
3. Caching and caching consistency.
WHAT WAS GFS WAS INFLUNECNED BY?
1. Hardware failure should be expected routinely.
2. Most files are changed by appending new data (rather than overwriting existing data).
3. Modularized software layer MapReduce sit on top of GFS to carry out large-scale parallel computations.
WHAT ARE THE ADVANTAGES OF DISK CACHES?
1. Reliable
2. Cached data kept on disk do not need to be fetched again while recovery.
ADVANTAGES OF MAIN MEMORY CACHES?
1. Can make workstations diskless.
2. Quicker data access.
3. Performance speed up in bigger memories.
4. Server c

Computer Architecture and Organization.pptxLearnersCoach
Computer architecture is the definition of basic attributes of hardware components and their interconnections, in order to achieve certain specified goals in terms of functions and performance. Computer Architecture refers to those attributes of a system that have a direct impact on the logical execution of a program. Examples:
- the instruction set
- the number of bits used to represent various data types
- I/O mechanisms
- memory addressing techniques
