Three Main Aspects:
1. Secrecy

A secure system is one where the features are relatively inaccessible to unauthorized users, therefore the system is protected.
A safe system needs to be secure, whereas, a secure system may not need to be safe depending on the application.
Security is a journey, not a destination. This is a security industry axiom that means we can strive for security, and by making this effort, we can put ourselves on a path to security. But while we may achieve a relative degree of security, our businesses will never be 100 percent secure—the destination we all strive for. Even Fort Knox, the White House and the New York Stock Exchange are vulnerable.

Identifying Potential Malicious Attacks, Threats, and Vulnerabilities.
The company is not alone in its dependence upon networking technology, which is essential to remaining competitive in today's video game software marketplace. The connectivity introduced by networking and computer technologies also introduces an enormous number of vulnerabilities that can compromise the confidentiality, integrity, and availability of the company's information. However, for each vulnerability there are countermeasures that can be implemented to would be intruders. Following are a series of vulnerability examples and countermeasure solutions that should be implemented by the company to avoid data loss and an information security incident.Existing Network Vulnerabilities
Wireless WPS Vulnerabilities
WPA2 is the most current version of standard based wireless network security to protect data confidentiality as it is transported over the wireless network. WPA2 includes major changes that address the shortcomings of both WPA and WEP. WPA2 includes the use of mandatory AES encryption, no longer supporting RC4 and TKIP. WPA2 also addresses most of the security issues that have been uncovered in WPA so that wireless networks protected with WPA2 can be considered as much more secure. However, as with all security measures, flaws are usually found and WPA2 is no different. Like WPA, the WPA2 implementation provides support for a feature called WPS or Wi-Fi Protected Setup, which is included to ease the setup and configuration of wireless network devices by leveraging a device specific pin number for use in automatically configuring pass-phrases between the AP unit and wireless clients, (Fitzpatrick, 2013). Unfortunately, this feature has a critical flaw that, with time (up to 10 hours are required), using software such as the free for download “Reaver” tool, penetration of a WPA2 protected wireless network is trivial. Hence, if implementing a WPA2 protected wireless network, make sure that all wireless network AP units are capable of disabling the WPS feature prior to deployment, (Fitzpatrick, 2013).
Wireless Network Confidentiality Vulnerabilities
Wireless network hackers use sniffer programs that contain additional, special “hacking” features designed to simplify the process of wireless network penetration. For example, the Airsnort wireless network sniffer is used by wireless hackers to sniff (capture) wireless network packets, collect those packets used in authentication exchange between an AP and its client devices. And then crack the pass ...

Why do you need a network security checklist? Your business faces threats on many fronts, and the more users, devices, and applications you add, the more vulnerable your network becomes. Whether your business is small or large, consider your network security requirements. Then follow our five-step network security checklist to create a holistic security solution to prevent breaches and address issues quickly.
Nowadays Organisations rely on data heavily to increase the efficiency and effectiveness of their business activities. It is necessary for organisations to secure their database from external attack in other to ensure confidentiality, integrity and availability. Different approaches to protect sensitive database are needed in an enterprise environment and can be combined together to strengthen an organization's security posture, while minimizing the cost and effort of data protection. Some of which are explained below. 1

Your introduction to the topic provides background information and prepares the reader for what follows. After discussing the OS vulnerabilities, you describe the threats to your environment. As you say, you can prevent weak password by setting up the security policies to enforce strong policies and this is so easy to implement that you can remove the threat right away. Instead of 'Week', try 'Weak'. You have very good material. The only item missed was the prioritization of the threats to decide which ones to mitigate. Good references and citations.

Operating System Security
Operating system security can be defined as the various sets of protection mechanisms or techniques employed by system administrators to prevent information theft and unauthorized resource access. All systems and especially in distributed systems require some measure of security that only allows authorized data manipulation and availability to employees of a company. Jinx will also need to secure its system to prevent both external and internal threats.
Services that are mostly focus on in system security include;
· Authentication: This is the validation of system servers or the identity of users or information/data senders within an organization.
· Availability: Authorized users of a system should be able to access information freely in addition to withholding it from unauthorized access. This also includes shared resources in the system.
· Authorization: This can also be referred to as Access Control. Organizations can limit the number of people access the network resources by simply verifying users when logging into the system. Using passwords and usernames is one way of controlling unauthorized access to computers and the system. However, authentication does not always guarantee a user full access to network resources or da ...
Security has been the number 1 issue for any IT industry and organiz.pdfanupambedcovers
Security has been the number 1 issue for any IT industry and organizations have to adopt to the
new security technology catering to their needs from time to time. Though the DBMS itself has
security features, however multiple features like SQL injection protection,vulnerability
assessments,user control activity etc features are still left unattended.Let us now see what are the
emerging security technologies in the protection of databases.
Protecting sensitive and confidential data of the organization is getting more and more difficult
as new threats are discovered. Database is a ever growing thing and their is a chance for the
presence of loopholes.The main problem when it comes to databases is the DBA should have the
view of all the data as a central controller and he should scour the database for any
vulnerabilities.VMT ( vulnerability management technology) is very useful to view the entire
database landscape and help the DBA to ensure his data of any exploitations.
Once the landscape is clearly scene a series of scans can be administered to see where the
sensitive or high protection needed data is present and using DAM technology (Database
monitoring technology) it is easy to protect the sensitive data effectively and add patches
wherever required. The technology also generates warnings and alerts on violations as it
monitors the database in real time. Most useful feature of using DAM is to collect information
about the use of DBMS which can help in audit purposes.It also provides database firewalls
which is similar to web application firewalls which can discard malicious activity,filter the
queries and have blacklist and whitelist feature as well.
Yes, software security is what people are after.However hardware security is needed wherever
software security cant protect.Nowadays cloud computing has emerged as the most powerful
technology where every information we have will be stored in remote servers and can be
accessed by us whenever needed. But the question arises about the security of the data. So, one
wonderful solution for this involves a hardware security systems where the dedicated chips are
inserted in the servers which can be overridden by the third parties via malicious attacks.These
chips provide security and security verification and makes the cloud system safe and reliable.
It is an obvious fact that providing hardware security for the device gives more confidence that
having a software security solution which can be accessed remotely and malware can come and
reside anywhere, But in these hardware systems there are only designated tasks and limited space
and malware cant even hide there.
Hardware security chips also manage physical problems.For example if there are fluctuations in
temperature,problems in electrical flow and breach of the casting then these chips can erase the
sensitive data.In this way these chips can protect themselves. There is also a facilty of every chip
having a unique digital signature and the user whe.
Discuss how a successful organization should have the followin.docxcuddietheresa
Discuss how a successful organization should have the following layers of security in place for the protection of its operations: information security management, data security, and network security.
Multiple Layers of Security
Marlowe Rooks posted Mar 13, 2020 9:54 AM
Looking at Vacca”s book chapter 1, “Information security management as a field is ever increasing in demand and responsibility because most organizations spend increasingly larger percentages of their IT budgets in attempting to manage risk and mitigate intrusions, not to mention the trend in many enterprises of moving all IT operations to an Internet-connected infrastructure, known as enterprise cloud computing (John R. Vacca, 2014)”. It is the organization responsibility to protect its business and its client information at all times. With that said I’m going to break down why companies need to have multiple layers of security and what types they should implement below.
The first layer is Information security management which can be from Physical Security, or Personnel Security. Physical Security can range from physical items, objects, or areas from unauthorized access and misuse. Personnel Security is to protect the individual or group of individuals who are authorized to access the organization and its operations. Some of the reason to implement Information Security is as follow:
· Decrease in downtime of IT systems
· Decrease in security related incidents
· Increase in meeting an organization's compliance requirements and standards
· Increase in customer satisfaction, demonstrating that security issues are tackled in the most appropriate manner
· Increase in quality of service
· Process approach adoption, which helps account for all legal and regulatory requirements
· More easily identifiable and managed risks
· Also covers information security (IS) (in addition to IT information security)
· Provides a competitive edge to an organization with the help of tackling risks and managing resources/processes
The second layer would be Data Security which can be refers to the process of protecting data from unauthorized access and data corruption throughout its lifecycle. Data security includes data encryption, tokenization, and key management practices that protect data across all applications and platforms. Some of the reason to implement Data Security is as follow:
· Cloud access security – Protection platform that allows you to move to the cloud securely while protecting data in cloud applications.
· Data encryption – Data-centric and tokenization security solutions that protect data across enterprise, cloud, mobile and big data environments.
· Web Browser Security - Protects sensitive data captured at the browser, from the point the customer enters cardholder or personal data, and keeps it protected through the ecosystem to the trusted host destination.
· Mobile App Security - Protecting sensitive data in native mobile apps while safeguarding the data end-to-end.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.
Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!

Different security measures for protecting data. I will also evaluate the different access control
methods for protecting I.T systems.

3. WAYSTO PROTECT AN I.T SYSTEM
Installing a firewall can block out hackers, whereas an anti-virus system can get rid
of those on your system, already.
This, if kept up-to-date is an effective means of overall system security, from the
outside world.
Unfortunately it cannot protect you against, internal theft from within the
business, for protection against this, a different security measure would have to
be put in place.
Most anti-virus software also includes spyware removal, this would make sure no
hackers can unwittingly gather your, or your customers data.
4. WAYSTO PROTECT AN I.T SYSTEM
Keeping software, which includes your OS, and internet browser, up-to-date.This
should fix any known bugs, and security flaws, which hackers may take advantage
of.
5. WAYSTO PROTECT AN I.T SYSTEM
Only allowing staff access to the resources needed.
This would minimise internal sabotage and theft, as the only data accessible is
that which is required for their job.
Although this protects data to some extent, other ways, which include physically
sealing ports shut, but more on this is explained later.
6. WAYSTO PROTECT AN I.T SYSTEM
If data has to be transferred, encrypt it!
Using encryption helps prevent the use of the data from theft, so if data has to be
transferred via a USB media device, then encrypting the data is vital. It makes
data unreadable until decrypted.
7. WAYSTO PROTECT AN I.T SYSTEM
In case of a server failure, have a backup.
If data is lost, a backup copy that is recent, will render the attack pointless. But
make sure that you have the most recent version, so no data is lost.
8. WAYSTO PROTECT AN I.T SYSTEM
Remove media correctly, make sure that all data removed is gone forever, for
instance, programs offer a secure way of deleting files. But another way is to
simply destroy the data at the source, the USB stick, or HDD, etc.
9. WAYSTO PROTECT AN I.T SYSTEM
Staff is a big security flaw among businesses.This can be minimised by training
them, and treating them with respect so that they wouldn’t want to steal from
you.
Staff can be trained to use a strong password, to not become susceptible to social
engineering, and to not be susceptible to spam emails, as these may contain
viruses.
Physically stealing USB ports on the computers can stop
any unwanted theft, it is a last resort which does work!
10. ACCESS CONTROL METHODS
Forcing password changes, and making them of suitable difficulty, with lower and
uppercase letters, numbers and symbols.
If updated regularly, and being completely different, this can be a very effective
means of protection against hackers.
This is a simple means of protection, and it should be vital and mandatory for
every business.
11. ACCESS CONTROL METHODS
Administrator (Admin user) rights.
By using the admin functionality (which is on most operating systems),
effectively; you can control and limit what the normal users of the system can and
can’t do.
A basic example of this, is to stop them changing passwords, and settings; this
prevents potential system sabotage.
If used in a server effectively, you can limit certain users to certain files, this is
described better on the next slide.
12. ACCESS CONTROL METHODS
A server may have one of the two (or both) types of “access controls”.
Discretionary access controls.
Mandatory access controls.
Discretionary access controls (DAC): It is called discretionary, because it is up to
the discretion of the author, as to whom he gives rites to the file(s). It gives certain
rights to certain users about whom can view and/or edit a document, etc.
Mandatory access controls (MAC): gives a device a level of security, and only files
that they can access have the same security, it is done through a series of
blacklists and whitelists, it is then used further for each individual user on the
system.
There aren’t without flaws though, the MAC setup is good for wired networks, but
wireless networks can still be tapped into by hackers, and they can mimic a
validated MAC through the registry (if using windows).
13. ACCESS CONTROL METHODS
Using the systems architecture, you can prioritise amounts of RAM, for certain
tasks, “thus isolating privileged processes from non-privileged processes”.
By doing so you can restrict access to parts of the system.
Overall, all of the access control methodfs described here, should not be used
alone, and there are flaws to quite a few of them (which are stated where
necessary). For the business, lots of these methods should be used together, to
stop any potential attacks.
