Question 1 - Brute-Forcing Passwords

The disruption ware challenged the SamSam’s operability status and suspended it through a compromise on the integrity, confidentiality, and availability of the networks, data, and systems that actually belongs to SamSam once. The initial techniques, tactics, and procedures or TTP could be a strong and unique password.

Technical preventative tool: Firewall

This can prevent malicious traffic from entering the Samsam network and is a physical preventative control/guard.

Technical detective control: Intrusion detective system

Since this is “after” the ransomware took place, this means a thorough audit trail should be led after this ransomware incident.

On an administrative level, it could be regular reviews and audits. Here are the mitigations:

Regular audit the RDP systems for remote communication;

It should be verified that there are no open RDP ports, say 3389 port;

Strong passwords need to be enacted

Two-factor authorization is a must

There should be a good back-up strategy

Question 2 - Clark-Wilson Model

The Clark-Wilson Model differs from Biba because it was developed with the intention to be sued for commercial activities, addressing all integrity goals. There is segregation of duties and the requisition of the audit must be enforced. As it implies Clark-Wilson model features on access control triple. The subjects are restricted when it comes to comparison with Biba.

Firstly, the prevention of unauthorised subjects from modifying objects. Secondly, the prevention of authorised subjects from making improper modifications. Thirdly, the maintenance of internal and external consistency. The Biba model only addresses Goal 1 whereas, the Clark-Wilson model addresses Goals 1, 2, and 3.

CDI - The customer’s bank account balances, are highly-integral, and needs more protective elements.

UDI - The customer’s bank accounts or profiles, is less integral and, therefore requiring more protection than any other banking elements.

TP - the facilities operational management of the fund in terms of withdrawals, transfers, and deposits, this is due to the transformation performance of data set patterns such as customers based account balances.

IVPs - the operations performed on decryption sequencing where the app server decrypts the transaction i.e. encrypted digest the hyperelliptic cryptosystem curve.

Question 3 - Dynamic Data Masking

Difference 1:

Data masking is a flavor based on two ingredients - Dynamic and static data

DDM or dynamic data masking is for transit sensitive data replacement despite the at-rest intact and unaltered original data which is part of SDM (static data masking).

Difference 2:

A full database city with masked information is created with additional space for copy. On the other hand, DDM is masked or on the fly where the query of the client and database response are changed with no requirement for additional server resources.

Example static over dynamic - At face value, static data really mask data as compared to the dynamic de-identification method.

Static permanently hides data, where high-quality data is available for application development and testing. It is best for GDPR, HIPAA compliance, and PCI as compared to dynamic masking.

Example dynamic over static DDM is best suites for object-level security psych as access duties. SQL database proxy is object-based security.

Question 4 - Educom Code

Issue 1 - illegal copying such as intellectual property and copyright problems. Academic writings have to follow academic integrity and encompass plagiarism constraints. The duplicating of someone’s hard work at no cost is an ethical violation.

Issue 2 - Privacy is challenged where the hacker jumps into someone’s private computer and access their information.

Issue 3 - The copyright may call for legal actions associated with such unethical acts. Copyright law protect software unauthorised copying. This may halter their academic year.

Issue 4 - No longer continuation or banning of their academic further year with the university. The violation of statement of principle about IP breaches legal and ethical conduct and can lead to penalties.

Solution: Educate students on the code of ethics. Considering the level of harm students may cause with a computer connected to an Internet, it is crucial to have code of ethics to keep them safe and to safely police the Internet (Forester & Morrison, 1994).

Solution: Educate students on the Educom code where academic course should teach student entrepreneurial values and respect for the rights of publishers, privacy, etc.

Question 5 - Preventative Layers

Preventative layers are intended to be executed before a dangerous occasion and decrease or potentially stay away from the probability and likely effect of a fruitful danger occasion. Instances of protection controls incorporate arrangements, gauges, forms, methods, encryption, firewalls, and physical hindrances.

Detective layers are intended to identify a dangerous occasion while it is happening and give help during examinations and reviews after the occasion has happened. Instances of investigator controls incorporate security occasion log observing, host and system interruption discovery of danger occasions, and antivirus recognizable proof of pernicious code.

Corrective layers are intended to moderate or breaking point the possible effect of a dangerous occasion once it has happened and recoup to ordinary tasks. Instances of remedial controls incorporate programmed evacuation of noxious code by antivirus programming, business congruity and recuperation plans, and host and system interruption counteraction of dangerous occasions.

Recovery The remaining danger must be overseen by reviewing, reinforcement, and recuperation systems upheld by general readiness and imaginative reactions.

Discussion 1

No. Defense-in-depth is a data affirmation methodology that gives numerous, excess protective measures in the event that a security control falls flat or a defenselessness is misused. It starts from a military methodology by a similar name, which tries to postpone the development of an assault, as opposed to vanquishing it with one in number line of barrier. Defense-in-depth cybersecurity use cases incorporate end-client security, item structure, and system security.

Discussion 2

Yes, that’s correct, I agree. Physical controls – These controls incorporate safety efforts that forestall physical access to IT frameworks, for example, security watches or bolted entryways.

Specialized controls – Technical controls incorporate safety efforts that secure system frameworks or assets utilizing particular equipment or programming, for example, a firewall apparatus or antivirus program.

Managerial controls – Administrative controls are safety efforts comprising of strategies or systems coordinated at an association s representatives, e.g., teaching clients to name delicate data as "private".

Furthermore, the accompanying security layers help ensure the singular features of your system:

Access measures – Access measures incorporate verification controls, biometrics, coordinated access, and VPN.

Workstation guards – Workstation protection measures incorporate antivirus and hostile to spam programming.

Information assurance – Data insurance strategies incorporate information very still encryption, hashing, secure information transmission, and encoded reinforcements.

Edge guards – Network border barriers incorporate firewalls, interruption discovery frameworks, and interruption avoidance frameworks.

Observing and counteraction – The checking and anticipation of system assaults include logging and reviewing system action, powerlessness scanners, sandboxing and security mindfulness preparing.

Question 7 - BIA 

Critical activities: BIA requires a ranking of critical business processes - from the "continuity" point of view - as a prerequisite to effectiveness. Then, analysts look at "what if" scenarios in which these critical processes are interrupted, slowed down, or unfeasible all together. A supercomputing ecosystem that is too small is not economically viable and cannot evolve fast enough to compete. Even if it is viable, but barely so, a few wrong decisions by company managers or national policymakers may destroy it. t is critical to coordinate the efforts of academia and industry to bring about breakthroughs in key technologies such as CPUs, storage devices, system architectures, and applications, in order to ensure the sustainable development of supercomputing.

Example 1: The significant specialized difficulties will be handled by a joint exertion of equipment and programming. For instance, the versatility issue will be tended to utilizing exceptionally solid equipment parts, by issue open-minded structure, and by quick disappointment recognition and recuperation plans. The customary programming checkpoint plan might be upgraded by quick NVM stockpiling and related quick setting changing equipment to adapt to the issue of exceptionally short MTBF.

Example 2: As Moore s Law moves toward its breaking point, the advancement of exascale supercomputing frameworks is confronting a progression of stupendous difficulties in the two advances and applications. Vitality is one of the most costly assets and the prevailing cost thing for running an enormous supercomputing office. For certain supercomputers, the absolute vitality cost of a couple of long periods of activity might be equivalent to the expense of the equipment framework. It is consistently perceived that exascale frameworks will be firmly compelled by vitality proficiency. In view of a 20 MW power financial plan, this requires the effectiveness of 50 GFlops/W.

RTO - RTO is identified with vacation and speaks to what extent it takes to reestablish from the episode until typical activities are accessible to clients. RTO is estimated in units of time. For RTO, the measurement is the measure of time that goes between application disappointment and full accessibility including information recuperation. The measurement is the measure of time between the loss of information and the previous reinforcement.

Discussion - Each RTO might be likely decided right off the bat in the BIA dependent on perfect recuperation targets. RTOs have frequently changed in accordance with mirror the money related real factors of executing a quick recuperation. Short RTOs will ordinarily require increasingly costly techniques adjusting the estimation of the data in danger and the expense of controls that can be higher. The Recovery Time Objective (RTO) is the length of time and an assistance level inside which a business procedure must be reestablished after a catastrophe so as to maintain a strategic distance from unsatisfactory outcomes related to a break incoherence. These actuals must be uncovered by calamity and business interruption practices. The Recovery Time Objective (RTO) is the span of time and a help level inside which a business procedure must be reestablished after a catastrophe so as to keep away from inadmissible results related to a break incoherence. Consistent Replication: Replication gives higher RPO ensures as the objective framework contains the reflected picture of the source. The RPA esteems rely on how quickly the progressions are applied and if the replication is simultaneous or non-concurrent. RPO is subject to how before long can the information on track/duplicated site be made accessible to the application.

Question 8 - Panic and Instigation Costs

Triage - Panic and instigation costs more and halter decision making of the victim, therefore ransom payments is included to triage or stop the attack. Triage your application once your attack is confirmed. A triage application list can assist in making compelling decisions during DDOS event.

investigations - The quicker you can check the event is a DDoS assault, the quicker you can react. Regardless of whether the blackout was definitely not brought about by a misconfiguration or other human mistake, there may at present be different clarifications that take after a DDoS event. For example, the Slashdot Effect happens when a specific page on your site is highlighted on a very well known gathering or blog. Your examination must guideline out such investigations.

Containment - At the point when a penetrate is first found, your underlying sense might be to safely erase everything so you can simply dispose of it. Notwithstanding, that will probably hurt you over the long haul since you ll annihilate important proof that you have to figure out where the to penetrate began and devise an arrangement to keep it from happening once more.

Rather, contain the penetrate so it doesn t spread and create additional harm to your business. In the event that you can, detach influenced gadgets from the Internet. Have a present moment and long term containment systems prepared. It s likewise acceptable to have a repetitive framework back-up to help reestablish business activities. That way, any undermined information isn t lost until the end of time.

This is additionally a decent an ideal opportunity to refresh and fix your frameworks, survey your remote access conventions (requiring compulsory multifaceted validation), change all client and managerial access certifications and solidify all passwords.

Analysis - This is where you decide if you ve been penetrated. A penetrate, or occurrence could start from a wide range of territories.

Inquiries to address (an analysis)

When did the occasion occur?

How was it found?

Who found it?

Have some other regions been affected?

What is the extent of the trade off?

Does it influence activities?

Has the source (purpose of section) of the occasion been found?

Tracking - Your association might be dependent upon legal resolutions that require a degree of announcing around digital assaults, penetrates, or even DDoS attacks. An assault log can help you in this circumstance, as you can track and allude to the log later during the reporting procedure.

Recovery - This is the way toward reestablishing and returning influenced frameworks and gadgets once again into your business condition. During this time, it s critical to get your frameworks and business tasks fully operational again without the dread of another break.

Inquiries to address

When would systems be able to be come back to creation?

Have frameworks been fixed, solidified and tried?

Could the framework be reestablished from a trusted back-up?

To what extent will the influenced frameworks be observed and what will you search for when checking?

What apparatuses will guarantee comparable assaults won t reoccur? (Record trustworthiness observing, interruption identification/security, and so on)
