This document summarizes key points from a lecture on information security. It describes the relationships between hackers and viruses, and how information security policies relate to security plans. It also provides examples of three primary security areas: authentication and authorization using passwords, smart cards, or biometrics; prevention and resistance using content filtering, encryption, and firewalls; and detection and response using intrusion detection systems, antivirus software, and unified threat management systems. Vulnerabilities discussed include network accessibility, hardware and software problems, and wireless challenges. Security threats include hackers, malware, spoofing, sniffing, and identity theft. The document emphasizes that people are the biggest security issue and that policies, plans, and technology work together as lines of defense.

Compusecuraphobia – The Fear of HOPING Your Computer is Secure - Course Technology Computing Conference
Presenter: Andrew Pond, Palm Beach State College
“Just because you're paranoid doesn't mean they aren't after you”. Ever pause just a moment before clicking past that security warning about an unsafe email? What about installation instructions that explicitly state to turn off your firewall and virus protection? I think, well that can't be right… hmmm. Gain an understanding of which security essentials should be introduced to students. This session will cover best practices that keep your Windows 8 computer safe and survey some of the threats that are directed toward the corporate world. Be prepared for the next tech trivia challenge, when the category covers SSL, IPSEC, Spoofing, Encryption, and more. Between the pop-up alerts on your computer to paranoia from the news, each of us should be thankful that we get through the day without having our identity stolen and our computer destroyed. The TSA thinks we are all safer if we take or shoes off while traveling. Really? Let us not take a similar approach with our own computer security.

Putting the SPARK into Virtual Training.pptxCynthia Clay
This 60-minute webinar, sponsored by Adobe, was delivered for the Training Mag Network. It explored the five elements of SPARK: Storytelling, Purpose, Action, Relationships, and Kudos. Knowing how to tell a well-structured story is key to building long-term memory. Stating a clear purpose that doesn't take away from the discovery learning process is critical. Ensuring that people move from theory to practical application is imperative. Creating strong social learning is the key to commitment and engagement. Validating and affirming participants' comments is the way to create a positive learning environment.
RMD24 | Debunking the non-endemic revenue myth Marvin Vacquier Droop | First ...BBPMedia1
Marvin neemt je in deze presentatie mee in de voordelen van non-endemic advertising op retail media netwerken. Hij brengt ook de uitdagingen in beeld die de markt op dit moment heeft op het gebied van retail media voor niet-leveranciers.
Retail media wordt gezien als het nieuwe advertising-medium en ook mediabureaus richten massaal retail media-afdelingen op. Merken die niet in de betreffende winkel liggen staan ook nog niet in de rij om op de retail media netwerken te adverteren. Marvin belicht de uitdagingen die er zijn om echt aansluiting te vinden op die markt van non-endemic advertising.
Memorandum Of Association Constitution of Company.pptseri bangash
www.seribangash.com
A Memorandum of Association (MOA) is a legal document that outlines the fundamental principles and objectives upon which a company operates. It serves as the company's charter or constitution and defines the scope of its activities. Here's a detailed note on the MOA:
Contents of Memorandum of Association:
Name Clause: This clause states the name of the company, which should end with words like "Limited" or "Ltd." for a public limited company and "Private Limited" or "Pvt. Ltd." for a private limited company.
https://seribangash.com/article-of-association-is-legal-doc-of-company/
Registered Office Clause: It specifies the location where the company's registered office is situated. This office is where all official communications and notices are sent.
Objective Clause: This clause delineates the main objectives for which the company is formed. It's important to define these objectives clearly, as the company cannot undertake activities beyond those mentioned in this clause.
www.seribangash.com
Liability Clause: It outlines the extent of liability of the company's members. In the case of companies limited by shares, the liability of members is limited to the amount unpaid on their shares. For companies limited by guarantee, members' liability is limited to the amount they undertake to contribute if the company is wound up.
https://seribangash.com/promotors-is-person-conceived-formation-company/
Capital Clause: This clause specifies the authorized capital of the company, i.e., the maximum amount of share capital the company is authorized to issue. It also mentions the division of this capital into shares and their respective nominal value.
Association Clause: It simply states that the subscribers wish to form a company and agree to become members of it, in accordance with the terms of the MOA.
Importance of Memorandum of Association:
Legal Requirement: The MOA is a legal requirement for the formation of a company. It must be filed with the Registrar of Companies during the incorporation process.
Constitutional Document: It serves as the company's constitutional document, defining its scope, powers, and limitations.
Protection of Members: It protects the interests of the company's members by clearly defining the objectives and limiting their liability.
External Communication: It provides clarity to external parties, such as investors, creditors, and regulatory authorities, regarding the company's objectives and powers.
https://seribangash.com/difference-public-and-private-company-law/
Binding Authority: The company and its members are bound by the provisions of the MOA. Any action taken beyond its scope may be considered ultra vires (beyond the powers) of the company and therefore void.
Amendment of MOA:
While the MOA lays down the company's fundamental principles, it is not entirely immutable. It can be amended, but only under specific circumstances and in compliance with legal procedures. Amendments typically require shareholder

Unveiling the Secrets How Does Generative AI Work.pdfSam H
At its core, generative artificial intelligence relies on the concept of generative models, which serve as engines that churn out entirely new data resembling their training data. It is like a sculptor who has studied so many forms found in nature and then uses this knowledge to create sculptures from his imagination that have never been seen before anywhere else. If taken to cyberspace, gans work almost the same way.
2. MAIN POINTS
Describing the relationships and differences between
hackers and viruses
Describing the relationship between information
security policies and an information security plan
Providing an example of each of the three primary
security areas: (1) authentication and authorization,
(2) prevention and resistance, and (3) detection and
response
3. • Why systems are vulnerable
– Accessibility of networks
– Hardware problems (breakdowns, configuration errors,
damage from improper use or crime)
– Software problems (programming errors, installation
errors, unauthorized changes)
– Disasters
– Use of networks/computers outside of firm’s control
– Loss and theft of portable devices
Systems Vulnerability and Abuse
Source: Laudon & Laudon (2016)
4. The architecture of a Web-based application typically includes a Web client, a server, and
corporate information systems linked to databases. Each of these components presents security
challenges and vulnerabilities. Floods, fires, power failures, and other electrical problems can
cause disruptions at any point in the network.
Source: Laudon & Laudon (2016)
Security Challenges & Vulnerabilities
5. • Internet vulnerabilities
– Network open to anyone
– Size of Internet means abuses can have wide impact
– Use of fixed Internet addresses …… creates fixed targets
for hackers
– E-mail, IM, ….
• Interception
• Attachments with malicious software
• Transmitting trade secrets
- Wireless security challenges
- Etc…
System Vulnerability and Abuse

6. Many Wi-Fi networks
can be penetrated
easily by intruders
using sniffer programs
to obtain an address to
access the resources of
a network without
authorization.

7. Protecting Intellectual Assets
• Organizational information is intellectual
capital - it must be protected
• Information security – The protection of
information from accidental or intentional
misuse by persons inside or outside an
organization
• Downtime – Refers to a period of time when a
system is unavailable
8. Security Threats Caused by Hackers and
Malware
• Hacker – Experts in technology who use their
knowledge to break into computers and computer
networks, either for profit / benefit or just motivated
by the challenge
– Black-hat hacker
– White-hat hacker
– Hactivist
– Cracker
– Cyberterrorist
9. Hackers
• White-hat hackers—work at the request of the system owners
to find system vulnerabilities and plug the holes
• Black-hat hackers —break into other people’s computer
systems and may just look around or may steal and destroy
information
• Hactivists—have philosophical and political reasons for
breaking into systems and will often deface the website as a
protest
10. Hackers
• Cracker—a hacker with criminal intent
• Cyberterrorists—seek to cause harm to people or to destroy
critical systems or information and use the Internet as a
weapon of mass destruction
11. – Viruses
• Malicious software program that attaches itself to
other software programs or data files in order to be
executed
– Worms
• Independent programs that copy themselves from one
computer to other computers over a network.
– Worms and viruses spread by
• Downloads (drive-by downloads)
• E-mail, IM attachments
• Downloads on Web sites and social networks
Malware (Malicious Software)
Source: Laudon & Laudon (2016)
12. • Denial-of-service attacks (DoS)
– Flooding server with thousands of false requests to crash
the network
• Distributed denial-of-service attacks (DDoS)
– Use of numerous computers to launch a DoS
Malware (Malicious Software)
Source: Laudon & Laudon (2016)
13. – Trojan horses
• Software that appears harmless but does something
other than expected
– Spyware
• Small programs install themselves in secret/by improper
means on computers to monitor user Web surfing
activities…..
Malware (Malicious Software)
Source: Laudon & Laudon (2016)
15. Security threats ….
• Malicious code includes a variety of threats (eg viruses,
worms, and Trojan horses)
• Spoofing is the forging of the return address on an email so
that the email message appears to come from someone other
than the actual sender. This is not a virus but rather a way by
which virus authors hide their identities as they send out
viruses.
16. Security threats ….
• A sniffer is a program or device that can monitor data traveling
over a network. Sniffers can show all the data being transmitted
over a network, including passwords and sensitive information.
Sniffers tend to be a favorite weapon in the hacker’s arsenal.
17. • Pharming
– Redirects users to a bogus Web page, even when individual
types correct Web page address into his or her browser
• Identity theft
– Theft of personal Information (social security ID, driver’s
license, or credit card numbers) to impersonate someone else
• Phishing
– Sending an e-mail messages that look like from a legitimate
businesses to ask users for confidential personal data and this
may include a link to a fake Web sites
Security threats ….

18. The First Line of Defense - People
• Organizations must enable employees, customers, and partners to
access information electronically
• The biggest issue surrounding information security is not a
technical issue, but a people issue
19. The First Line of Defense - People
• The first line of defense an organization should follow
to help combat insider issues is to develop information
security policies and an information security plan
– Information security policies – identify the rules required to
maintain information security
– Information security plan – details how an organization will
implement the information security policies
20. The Second Line of Defense - Technology
• There are three primary information technology security
areas
21. Authentication and Authorization
• Authentication – A method for confirming users’identities
• Authorization – The process of giving someone permission to
do or have something
• The most secure type of authentication involves
1. Something the user knows
2. Something the user has
3. Something that is part of the user
22. Something the User Knows Such As a User ID and
Password
• This is the most common way to identify
individual users and typically contains a
user ID and a password
• This is also the most ineffective form of
authentication
• Over 50 % of help-desk calls are
password related
23. • Smart cards and tokens are more effective
than a user ID and a password
– Tokens – Small electronic devices that
change user passwords automatically
– Smart card – A device that is around the
same size as a credit card, containing
embedded technologies that can store
information and small amounts of software to
perform some limited processing
Something the User has Such As Smart cards and
tokens
24. Something That Is Part Of The User Such As a
Fingerprint or Iris
• This is by far the best and most effective way to
manage authentication
– Biometrics – The identification of a user based on a
physical characteristic, such as a fingerprint, iris,
voice, or handwriting
• Unfortunately, this method can be costly and intrusive
25. Prevention and Resistance
• Downtime can cost an organization anywhere from
$100 to $1 million per hour
• Technologies available to help prevent and build
resistance to attacks include
1. Content filtering
2. Encryption
3. Firewalls
26. Prevention and Resistance
• Content filtering - Prevents emails containing sensitive
information from transmitting and stops spam and viruses
from spreading
27. Prevention and Resistance
• If there is an information security breach and the
information was encrypted, the person stealing the
information would be unable to read it
– Encryption
– Public key encryption (PKE)
28. Prevention and Resistance
Encryption – scrambles information into an alternative form
that requires a key or password to decrypt the information
Public key encryption (PKE) – an encryption system that
uses two keys: a public key for everyone and a private key for
the recipient
29. A public key encryption system can be viewed as a series of public and private keys that lock data
when they are transmitted and unlock the data when they are received. The sender locates the
recipient’s public key in a directory and uses it to encrypt a message. The message is sent in encrypted
form over the Internet or a private network. When the encrypted message arrives, the recipient uses his
or her private key to decrypt the data and read the message.

31. Firewall:
– Combination of hardware and software that prevents
unauthorized users from accessing private networks
Prevention and Resistance
Source: Laudon & Laudon (2016)
32. The firewall is placed between the firm’s private network and the public Internet or another distrusted
network to protect against unauthorized
traffic.

A Corporate Firewall
33. Detection and Response
• If prevention and resistance strategies
fail and there is a security breach, an
organization can use detection and
response technologies to mitigate the
damage
34. • Intrusion detection systems:
– Monitors hot spots on corporate networks to detect and
deter intruders
– Examines events as they are happening to discover
attacks in progress
• Antivirus and antispyware software:
– Checks computers for presence of malware and can often
eliminate it as well
– Requires continual updating
• Unified threat management (UTM) systems
Detection and Response
