Data security in the age of GDPR – most common data security problemsExove
This document discusses common data security problems that can result in fines under the GDPR and how to address them, including:
1) Accidental disclosure of data, such as unauthenticated access to files or APIs, can be avoided by requiring authentication for all data access and properly configuring access settings.
2) Lacking internal access controls allows users to access too much information; these issues can be fixed by implementing and enforcing internal access controls.
3) Targeted attacks by professional criminals are difficult to prevent, but risks can be reduced by limiting data and system access, employing automated checks, and only allowing verified file changes.
Blockade.io : One Click Browser DefenseRiskIQ, Inc.
When thinking of modern attacks, the web browser is still one of the top delivery vehicles. Whether it’s displaying an email or facilitating a link-redirection or merely serving a web page, browsers aid in the attack process. Despite their popularity, many companies focus their efforts defending the operating system, inspecting the network or attempting to keep up with threats through delivered feeds.
In order for any tool to gain adoption, it not only has to be useful, but also needs to easily fit into a user’s workflow. Using native browser interfaces, we’ve created a set of open source browser extensions that not only detect malicious activity, but block it entirely. More importantly, this functionality is delivered in a one-click package and doesn’t require any technical knowledge in order to successfully function. Users are able to take advantage of hosted repositories of data or run their own data node and updates are automatic.
This presentation will introduce the browser extension details, highlight how they function and inform users how they could take advantage of this functionality in their organization. No security solution is perfect, but bringing blocking capabilities to the browser without requiring any user change guarantees even the least technical of users can be protected. Originally developed with non-profit and smaller businesses in mind, these security browser extensions can bring peace of mind to any size organization, free of charge.

This document discusses various network security issues and methods. It covers topics like unauthorized access, malware, denial of service attacks, security methods like access rights and firewalls, and ways to protect against threats such as encryption, backups, and anti-virus software. Network security is important because when computers are connected, there are increased risks from other devices gaining access without permission. Hackers, viruses, and other threats can read or damage data if networks are not properly secured.
Cloud computing allows users to access computing resources over the internet rather than using local hardware. It provides capabilities for organizations to access data from anywhere on any device in a scalable and cost-effective manner. There are different types of cloud services (IaaS, PaaS, SaaS) and deployment models (private, public, hybrid, community). Security managers must ensure compliance with relevant laws and privacy standards when using cloud computing.

This document outlines the process for investigating accidents and incidents. It defines an accident investigation as an important part of a safety management system that highlights why accidents occur and how to prevent them. The primary goals of an investigation are to identify the immediate and root causes of events and implement remedies to improve safety. All accidents, regardless of severity, should be investigated to some degree to identify common causes and trends. The stages of an investigation include dealing with immediate risks, selecting an investigation level, investigating the event, recording and analyzing results, and reviewing the process. Thorough observation, documentation review, and interviews are important for determining causes. Remedial actions should follow a hierarchy of risk control from elimination to engineering to administrative controls.
This document discusses the Muslim cultural practice of saying "inshallah" or "if God wills" when committing to future plans or events. It argues that using "inshallah" should only be done when one is fully committed and plans to do everything possible to fulfill the commitment. Otherwise, it is misleading others about one's intentions and values. The document recommends that Muslims be truthful when making commitments by acknowledging if they are uncertain about attending rather than using "inshallah" casually. Being punctual and reliable in commitments is presented as an important Muslim value.
An accident investigation aims to improve safety by exploring the causes of events and identifying remedies. All accidents, regardless of severity, should be investigated to some degree to understand root causes. A thorough investigation involves collecting evidence from the scene, documents, and witness interviews without blame. The investigation process determines immediate causes like unsafe acts or conditions, as well as underlying causes involving management systems. The results are recorded and analyzed to identify corrective actions and prevent future occurrences.
This document provides excerpts from the Bible discussing monotheism. It includes passages from Isaiah 44 describing how God chose Israel and will help them, pouring out blessings. It discusses how the Lord is the first and last, the only God, and how those who make idols will be ashamed. The excerpts condemn idol worship and praise God as the redeemer of Israel.
The document discusses global climate change and summarizes the findings of the Intergovernmental Panel on Climate Change (IPCC). The IPCC concludes that warming of the climate is occurring and is very likely due to human-caused greenhouse gas emissions. The IPCC reports observe increasing global temperatures, melting ice and snow, and rising sea levels. Greenhouse gas levels are at the highest levels in hundreds of thousands of years and will likely cause continued warming and sea level rise for centuries. The document also notes potential effects like increased wildfires, species extinctions, and more severe heat waves.
The document discusses access control, including definitions, principles, policies, requirements, and basic elements. It covers discretionary access control models, protection domains, UNIX file access control using inodes, traditional UNIX controls like setuid and sticky bits, and newer access control lists in UNIX.
The document discusses various methods for user authentication, including passwords, tokens, and biometrics. It describes strategies for improving password security, such as password selection techniques, password files, and shadow passwords. It also covers token-based authentication using memory cards and smart cards. Biometric authentication using physical characteristics like fingerprints is explored. Finally, it summarizes challenges with remote user authentication and provides examples of password, token, and biometric protocols.
User authentication is the process of verifying an identity claimed by a system entity. There are four main means of authenticating a user's identity: something the user knows (e.g. password), something the user possesses (e.g. smart card), something the user is (e.g. fingerprint), and something the user does (e.g. typing rhythm). Password authentication is widely used but vulnerable to dictionary attacks, password guessing, workstation hijacking, and exploiting multiple password use or user mistakes. Techniques like password hashing with salts and account lockouts help strengthen password authentication against cracking attempts.
The document discusses e-marketing planning and provides guidance on creating an e-marketing plan. It introduces the SOSTAC framework for e-marketing planning and emphasizes the importance of situation analysis, including demand analysis, competitor analysis, intermediary analysis, and an internal marketing audit. These analyses provide critical inputs to define objectives, strategies and tactics for the e-marketing plan. The document also notes that a separate e-marketing plan is typically required to fully capture online marketing opportunities and customer demand.
Cryptographic tools discussed include symmetric encryption using secret keys, public-key encryption using key pairs, hash functions for message authentication and digital signatures, and random numbers. Symmetric encryption is the most commonly used prior to public-key encryption due to efficiency. Hash functions are used to create digital signatures by encrypting a hash with a private key. Digital envelopes allow message protection without pre-arranged keys. Random numbers must be unpredictable and independent to be cryptographically secure.
This lecture discusses various cryptographic tools including symmetric encryption, public key encryption, digital signatures, and secure hash functions. Symmetric encryption uses a shared secret key between the sender and receiver. Cryptanalysis attacks try to deduce plaintext or keys by exploiting algorithm characteristics or known plaintext/ciphertext pairs. The lecture reviews common symmetric algorithms like DES, 3DES, and AES and discusses block vs stream ciphers. It also covers practical issues like encryption modes and the advantages of stream ciphers. Finally, it briefly discusses random numbers, quantum computing risks to encryption, and Gnu Privacy Guard (GPG).

In the rapidly evolving landscape of technologies, XML continues to play a vital role in structuring, storing, and transporting data across diverse systems. The recent advancements in artificial intelligence (AI) present new methodologies for enhancing XML development workflows, introducing efficiency, automation, and intelligent capabilities. This presentation will outline the scope and perspective of utilizing AI in XML development. The potential benefits and the possible pitfalls will be highlighted, providing a balanced view of the subject.
We will explore the capabilities of AI in understanding XML markup languages and autonomously creating structured XML content. Additionally, we will examine the capacity of AI to enrich plain text with appropriate XML markup. Practical examples and methodological guidelines will be provided to elucidate how AI can be effectively prompted to interpret and generate accurate XML markup.
Further emphasis will be placed on the role of AI in developing XSLT, or schemas such as XSD and Schematron. We will address the techniques and strategies adopted to create prompts for generating code, explaining code, or refactoring the code, and the results achieved.
The discussion will extend to how AI can be used to transform XML content. In particular, the focus will be on the use of AI XPath extension functions in XSLT, Schematron, Schematron Quick Fixes, or for XML content refactoring.
The presentation aims to deliver a comprehensive overview of AI usage in XML development, providing attendees with the necessary knowledge to make informed decisions. Whether you’re at the early stages of adopting AI or considering integrating it in advanced XML development, this presentation will cover all levels of expertise.
By highlighting the potential advantages and challenges of integrating AI with XML development tools and languages, the presentation seeks to inspire thoughtful conversation around the future of XML development. We’ll not only delve into the technical aspects of AI-powered XML development but also discuss practical implications and possible future directions.

Webinar: Designing a schema for a Data WarehouseFederico Razzoli
Are you new to data warehouses (DWH)? Do you need to check whether your data warehouse follows the best practices for a good design? In both cases, this webinar is for you.
A data warehouse is a central relational database that contains all measurements about a business or an organisation. This data comes from a variety of heterogeneous data sources, which includes databases of any type that back the applications used by the company, data files exported by some applications, or APIs provided by internal or external services.
But designing a data warehouse correctly is a hard task, which requires gathering information about the business processes that need to be analysed in the first place. These processes must be translated into so-called star schemas, which means, denormalised databases where each table represents a dimension or facts.
We will discuss these topics:
- How to gather information about a business;
- Understanding dictionaries and how to identify business entities;
- Dimensions and facts;
- Setting a table granularity;
- Types of facts;
- Types of dimensions;
- Snowflakes and how to avoid them;
- Expanding existing dimensions and facts.

AI 101: An Introduction to the Basics and Impact of Artificial IntelligenceIndexBug
Imagine a world where machines not only perform tasks but also learn, adapt, and make decisions. This is the promise of Artificial Intelligence (AI), a technology that's not just enhancing our lives but revolutionizing entire industries.
2. Topics Covered
●
What is a security Policy
●
Unenforceable Policies
●
Email and web filtering
●
Approaches to Policy Development
●
ACL management based on Policies
3. What is a Security Policy ?
●
Organizations usually have unwritten policies.
●
These are known as tacit policies.
●
Formal Security policy development requires
understanding authority, scope, expiration,
specificity and clarity.
●
Developing and implementing such policies is
not easy.
4. What it does.
●
A security policy establishes what must be done
to protect information stored on computers. A
well written policy contains sufficient definition
of “what” to do so that the “how” can be
identified and measured or evaluated.
5. The big deal of “access control”
●
The problem is that the “network” is designed
and expected to provide access.
●
The lack of control requires allows people to do
things which result in losses or destruction of
valuables of an organization.
6. The big deal of “access control”
●
Access pertains to accessibility, providing
services, performance, and ease of use.
●
Control focuses on denial of unauthorized service
or access, separation, integrity and safety.
7. IT Security Policies
●
IT security policies (including network security
policies) are the foundation, the bottom line, of
information security within an organization. As
such, it is well worth considering a few questions
with respect to them:
●
Are they comprehensive enough?
●
Are they up to date?
●
Do you deliver them effectively ?
11. Examples
●
Fragmented packets do not have port numbers in
their headers.
●
A simple firewall cannot decide wether to accept
or reject.
12. Examples
In such ambiguous cases a firewall can
●
Consult the state table to see if the fragment is
part of an existing connection.
●
Buffer the fragment to complete the IP packet
then decide.
●
Let the fragment through and limit speeds of such
packets to reduce DOS attack possibilities.
13. Examples
●
If outbound ICMP unreachables are disabled
then let the fragment through.
●
Drop the packet and make the sender retransmit.
14. Complexity
●
Firewall GUIs may look simple.
●
However there is a large amount of complexity
underneath the simple looking interface.
●
Sometimes we may be granting access when we
are thinking we are applying control.
●
These cases are called unenforcable policies.
15. Unenforceable Policy
●
In the main frame days there used to be policies
like : “no personal use of the organization's
computers”
●
Since 1985 and the times of distributed network
computing. Such policies have become
unenforceable.
16. Email Example
●
You are working on a document and you check
an email then you see that someone sent you a
greeting card. You visit the card site or find
something interesting on google. You forget the
document for over an hour.
●
The policy is written but can not be enforced.
17. Problems with such policies
●
If you have an unenforceable administrative
policy, then people are encouraged to ignore or
push the rules.
●
In fact one reason why cracking is so prevalent is
that any laws against it are virtually
unenforceable, especially because many courts
have ruled that the reconnaissance phase,
scanning, is legal.
18. Another example
●
Report all virus infections.
●
Usually a virus is cleaned and people get on with
life without bothering to report it.
●
With automated monitoring tools the reports can
go from seven manual reports per year to more
than a thousand automated reports.
19. Unusual user questions
●
What if my wife sends me an email ? Is it okay to
read it ?
●
Can I check my stocks at lunch ?
20. Answers
●
Due to such questions, something called a limited
personal use policy is created.
●
Basically this limited use policy states things like
:
●
You may use the computers for personal use.
BUT. Do not ask. Do not tell. Do not send chain
letters, do fund raising, or pass files which cause
useless discussions to start.
21. Content Filtering
●
Client Side content filters have matured but
require a subscription.
●
Proxy server based content filters are a better
solution according.
22. Back to centralization
●
A lot of the problems arising out of the pervasive
computing is that many computers are running
independently.
●
Administrators are reluctant to monitor such a
large number of computers.
23. Back to centralization
●
By centralizing the servers to Web Based
softwares, Email clients, groupware and also
using Terminal servers with centralized
computing, the problem of unenforceable policies
is reduced dramatically.
24. Email Server
●
A web Based central mail server either hosted in
the company or in a third party offers a deterrent
because all employees know that their email can
be monitored.
●
Filtering non company email is easy because
there is only one domain.
●
Domains like yahoo and hotmail can be blocked.
25. Email Server
●
Email is a very large leak of important
confidential documents.
●
This is mainly due to the fact that most
companies do not clearly state that giving
information out is an offence. New people
entering the workforce are use to copyright
violations and do not think of sharing such
information as an offence.
26. Email Server
●
Before an employee has finished his or her tea,
they shall attach any file you request them to and
never remember that they they sent the file.
●
Outlook is a user friendly program which accepts
email from anyone and runs any code embedded
just by reading the email. You do not need to
double click an attachment.
27. HTML Aware Email Clients
●
Companies currently still allow the use of HTML
aware macro extendable programs such as
outlook.
●
What is required are programs which do not
download and execute HTML code whenever an
email is received.
●
Hardly any organization has the need for such
features.
28. Gmail type Javascript
●
Gmail provides the best example of client side
scripting.
●
Their email software is web based and feels like a
local email client for more than 90% of the
world's users.
●
No viruses are possible automatically because the
HTML is opened by server side softwares.
29. Client Side Backups
●
Administrators usually backup their servers and
in an emergency or drill situation do not bother
about data on the client machines.
●
Examples are : The contact list on the marketing
manager's harddisk or the top management's
recent notes.
30. Media Leaks
●
People move data on Floppies, CDRW, Tapes,
Flash drives, even harddisks.
●
Companies usually have a policy that states that
all media needs to be declared, however random
spot checks are rarely done in such places.
31. Business Continuity
●
Examples of lost credit card by Bank of America
on UPS routes exemplifies the need for
encryption of backups.
●
Business continuity requires response times less
than the usual 3 to 5 hours for cold sites to come
back online.
32. Backdoors
●
Modems can breach security.
●
Monitoring of Analog lines is touch.
●
Monitoring the digital lines is better.
●
Even the serial port monitor which is cost
effective can be fooled by XON/XOFF
encodings.
●
Beware of hardware keyloggers disguised as
inductance coils.
33. Proxy Server
●
Content filtering in the proxy server prevents
access to denied sites.
●
If thin clients are used then http tunnels and DNS
tunnels are possible but easily monitorable.
●
Also http tunnels shall be intentional.
34. Applications
●
Virus management and spywares shall be reduced
dramatically because the servers shall be
monitored by the administrators very carefully.
●
Usually heavy work can be done on Linux based
servers while other client can use VNC or other
terminal server protocols like RDP.
35. Policies Change
●
As requirements change, policies change to meet
them.
●
Sooner or later the firewall or content filtering
managers shall have a controversy as to what to
allow or deny.
●
To avoid this problem updated, approved and
signed policies need to be circulated to the ACL
managers.
36. Usual Issues
●
The scope of information security is not organization wide.
●
Some noncentral information systems may not be well managed
●
Some third party systems are not appropriately protected
(Example TCS terminals or other service providers terminals)
●
Information security for personal computers is weak
●
Insufficient resources are focused on information security
●
Policy development is not receiving sufficient attention
37. Many approaches
●
There are many approaches to developing
policies.
●
The recommended method these days is a risk
based approach.
38. Risk Based Approach
In the risk based approach :
●
We identify the risk
●
Communicate what is learned to upper
management
●
Update or create the security policy
●
Figure out how to measure compliance to the
policy provided.
39. Identifying Risks
●
What data from a different source used by the
organization shall really hurt if it was not
available ?
●
Find out what the Internet is being currently
being used for. This needs to be done quitely.
●
Since there is no policy, the users are not doing
anything wrong.
40. Keep the users calm.
●
Explain to the users that you are simply trying to
establish a baseline and not get anyone into
trouble.
●
When some users ask why they need to follow a
policy, then a written, signed and dated policy
from upper management is all it takes to get most
people to accept the idea that things need to be
done slightly differently.
41. Communicating Ideas
●
Rule number one of explaining things to upper
management.
●
You need to realize that they do not understand
the obvious differences between ATM & ATM or
DOS & DOS & DDOS.
●
Keep the communication simple, balanced and
fairly consise.
42. Avoid Individual Attacks
●
In the presentation do not mention any person by
name. Management may take that as a personal
attack and dismiss all that you have researched.
●
Keep the tone general.
●
Provide problems found and implications.
●
Provide examples where financial losses were
incurred.
43. Offer Options
●
Provide the management options for managing
the risks.
●
It is probably better to use more than one anti
virus software on the mail server.
●
If management decides to buy only one then
provide enough information for them to be able
to make a reasonable choice.
44. Written copy.
●
Do not present as a discussion only.
●
Provide a written copy to everyone involved in
the process.
45. Leadership Required
●
Hire an information security director to lead the organization wide
efforts to raise information security readiness.
●
Develop and implement an information security plan
●
Develop effective working relationships with
– other central offices
– all branches,
– Suppliers and vendors being interfaced with.
– Assist branches in benefiting from what has already been
accomplished at other branches.
– Develop an organization wide information security forum for
informationsharing and solutionseeking
46. The Problem
●
Software systems fail to
adequately address security
and privacy issues during
analysis & design.
47. Challenges
●
Difficult to apply traditional software
requirements engineering techniques to systems
in which
– policy is continually changing the need to respond to
the rapid introduction of new technologies which may
compromise those policies
– increasing external pressure to publicize one’s
information and security practices
●
Government now requires compliance with laws (e.g. Statebank
Banking Regulations, WTO, Basel II)
48. Addressing the Problem
●
Goal:
– Use effective approaches to ensure security
and privacy requirements coverage
●
Strategy
– apply scenario analysis and goaldriven analysis strategies
– perform risk and impact assessments to ensure system requirements align
with organizational policies
– analyze security and privacy policies
– ensure compliance with governing laws
50. Common Policy Problems
●
Nonconformance to “standard”
– Organisation for Economic Cooperation & Development
– Federal Trade Commission
– State Bank Regulations.
– Fair Information Practices
●
Ambiguity and misplaced trust
– Policies are difficult to find/interpret
– Failure to implement policy
– Inconsistencies are common
51. Requirements Inspection
●
Inspection artifacts:
– Requirements
– Security policies
– Privacy policies
●
Process:
– Use heuristics to crosscompare requirements, privacy policies and security
policies to identify and resolve conflicts and ambiguities
●
Helps identify inconsistencies across requirements and policies
●
Example:
– Privacy Policy: No sharing of PII w/ 3rd parties
– Requirement: Use PII to complete transaction
52. Potential Relationships and Conflicts
General Relat ionships:
Constrains Item A constrains Item B.
Depends Item A depends upon Item B.
Supports Item A supports (in some manner) Item B.
Operationalizes Item A operationalizes Item B.
Conflict s:
Terminology Complete clash between terminology used within
documentation.
Differences between terminology used within
Ambiguity documentation in which there is a need to qualify or
further refine some term.
Incomplete Ambiguity A specialized form of ambiguity that results from terms
being left out of the documentation.
Potential There exists even the slightest possibility for a conflict to
occur, as the statements are open to misinterpretation.
Definite A conflict will occur if the requirements and policies are
implemented as written.
53. Compliance: Policy Statements &
Requirements
MAINTAIN ENSURE MAINTAIN
member content member data
entrance to visibility to history (for user
server members customization)
only
Authentication is required for access
to the commerce Web server.
All member account information will
be kept confidential and used for
#
internal business purposes only.
The firewall should be configured to
limit data access to authorized
member users.
54. Challenges
●
How can we guarantee:
– policy complies with law?
– system requirements comply with policy?
– information handling adheres to policy and system requirements?
●
How can policy be associated with data to ensure policies survive
system boundaries?
– users can’t determine whether a site is in compliance with its policy
because many operations are hidden from view.
55. Before making an ACL
●
The most important step take before making an
access control list of a firewall is to first examine
the site's policy before making a ruleset.
●
The general rule of thumb is to keep your rules to
less than 20.
●
The more the fine grained control required the
longer the rule sets shall be.
56. Documenting ACLs
●
Try to group ACLs into logical areas. Much like
the idea of procedures which was created to avoid
the problems of spaghetti code in the 1960s and
1970s.
●
Document the relationship between the policy
and the Ruleset.
57. TCP Port 80
●
SOAP, HTTP, and a lot of other things use port
80. Even spywares use it.
●
The current status is that you should not block
this.
●
You can use deep packet analysis to find
spywares and http tunnels.
●
Company policy should clearly state what shall
happen to a person found using tunnels.
58. What was covered.
●
A brief idea of some of the things which need to
be taken into account in developing a security
policy were mentioned.
●
We hope you were able to glean at least the
basics as to why unwritten agreements need to be
converted into formal policies.
59. A lot more....
●
There are thousands of other things which need to
be catered for in depth in the process of
developing a comprehensive Security Policy.
