Climate Impact of Software Testing at Nordic Testing DaysKari Kakkonen
My slides at Nordic Testing Days 6.6.2024
Climate impact / sustainability of software testing discussed on the talk. ICT and testing must carry their part of global responsibility to help with the climat warming. We can minimize the carbon footprint but we can also have a carbon handprint, a positive impact on the climate. Quality characteristics can be added with sustainability, and then measured continuously. Test environments can be used less, and in smaller scale and on demand. Test techniques can be used in optimizing or minimizing number of tests. Test automation can be used to speed up testing.
Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdfPaige Cruz
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:

3. The combination of space, time, and strength that must be considered
as the basic elements of this theory of defense makes this a fairly
complicated matter. Consequently, it is not easy to find a fixed point
of departure.
— On War, Carl Von Clausewitz
The art of war teaches us to rely not on the likelihood of the enemy's
not coming, but on our own readiness to receive him; not on the
chance of his not attacking, but rather on the fact that we have
made our position unassailable.
—The Art of War, Sun Tzu
4. Computer Security
Concepts
• Before the widespread use of data processing equipment, the security of
information valuable to an organization was provided primarily by physical
and administrative means
• With the introduction of the computer, the need for automated tools for
protecting files and other information stored on the computer became evident
• Another major change that affected security is the introduction of distributed
systems and the use of networks and communications facilities for carrying
data between terminal user and computer and between computer and
computer
• Computer security
• The generic name for the collection of tools designed to protect data and to thwart
hackers
• internet security (lower case “i” refers to any interconnected collection of
network)
• Consists of measures to deter, prevent, detect, and correct security violations that
involve the transmission of information

to unauthorized individuals
• Privacy
• Assures that individuals control or influence what information related to them may
be collected and stored and by whom and to whom that information may be
disclosed
Confidentiality
• Data integrity
• Assures that information and programs are changed only in a specified and
authorized manner
• System integrity
• Assures that a system performs its intended function in an unimpaired manner,
free from deliberate or inadvertent unauthorized manipulation of the system

that generates the
requirement for
actions of an entity
to be traced uniquely
to that entity

patient and expose the
hospital to massive liability
A Web site that offers a
forum to registered users to
discuss some specific topic
would be assigned a
moderate level of integrity
An example of a low-
integrity requirement is an
anonymous online poll
Availability
The more critical a
component or service, the
higher the level of
availability required
A moderate availability
requirement is a public
Web site for a university
An online telephone
directory lookup
application would be
classified as a low-
availability requirement
11. Computer Security
Challenges
• Security is not simple
• Potential attacks on the
security features need to be
considered
• Procedures used to provide
particular services are often
counter-intuitive
• It is necessary to decide where
to use the various security
mechanisms
• Requires constant monitoring
• Is too often an afterthought
• Security mechanisms typically
involve more than a particular
algorithm or protocol
• Security is essentially a battle
of wits between a perpetrator
and the designer
• Little benefit from security
investment is perceived until a
security failure occurs
• Strong security is often
viewed as an impediment to
efficient and user-friendly
operation
12. OSI Security
Architecture
• Security attack
• Any action that compromises the security of information
owned by an organization
• Security mechanism
• A process (or a device incorporating such a process) that is
designed to detect, prevent, or recover from a security attack
• Security service
• A processing or communication service that enhances the
security of the data processing systems and the information
transfers of an organization
• Intended to counter security attacks, and they make use of one
or more security mechanisms to provide the service
14. Security
Attacks
•A means of classifying security
attacks, used both in X.800 and RFC
4949, is in terms of passive attacks and
active attacks
•A passive attack attempts to learn or
make use of information from the
system but does not affect system
resources
•An active attack attempts to alter
system resources or affect their
operation
15. Passive
Attacks
• Two types of passive
attacks are:
• The release of message
contents
• Traffic analysis
• Are in the nature of
eavesdropping on, or
monitoring of, transmissions
• Goal of the opponent is to
obtain information that is
being transmitted
16. Active Attacks
• Involve some modification of the
data stream or the creation of a
false stream
• Difficult to prevent because of the
wide variety of potential physical,
software, and network
vulnerabilities
• Goal is to detect attacks and to
recover from any disruption or
delays caused by them
• Takes place when one entity
pretends to be a different entity
• Usually includes one of the other
forms of active attack
Masquerade
• Involves the passive capture of a
data unit and its subsequent
retransmission to produce an
unauthorized effect
Replay
• Some portion of a legitimate
message is altered, or messages
are delayed or reordered to
produce an unauthorized effect
Modification
of messages
• Prevents or inhibits the normal
use or management of
communications facilities
Denial of
service
17. Security Services
• Defined by X.800 as:
• A service provided by a protocol layer of communicating open
systems and that ensures adequate security of the systems or of
data transfers
• Defined by RFC 4949 as:
• A processing or communication service provided by a system
to give a specific kind of protection to system resources
18. X.800 Service Categories
• Authentication
• Access control
• Data confidentiality
• Data integrity
• Nonrepudiation
20. Authentication
• Concerned with assuring that a communication is
authentic
• In the case of a single message, assures the recipient that
the message is from the source that it claims to be from
• In the case of ongoing interaction, assures the two
entities are authentic and that the connection is not
interfered with in such a way that a third party can
masquerade as one of the two legitimate parties
Two specific authentication services are defined in X.800:
• Peer entity authentication
• Data origin authentication
21. Access Control
• The ability to limit and control the access to host
systems and applications via communications links
• To achieve this, each entity trying to gain access must
first be indentified, or authenticated, so that access
rights can be tailored to the individual
22. Data Confidentiality
• The protection of transmitted data from passive attacks
• Broadest service protects all user data transmitted between
two users over a period of time
• Narrower forms of service include the protection of a single
message or even specific fields within a message
• The protection of traffic flow from analysis
• This requires that an attacker not be able to observe the source
and destination, frequency, length, or other characteristics of
the traffic on a communications facility
23. Data Integrity
Can apply to a stream of messages, a single
message, or selected fields within a message
Connection-oriented integrity service deals with a
stream of messages and assures that messages are
received as sent with no duplication, insertion,
modification, reordering, or replays
A connectionless integrity service deals with
individual messages without regard to any larger
context and generally provides protection against
message modification only
24. Nonrepudiation
• Prevents either sender or receiver from denying a
transmitted message
• When a message is sent, the receiver can prove that the
alleged sender in fact sent the message
• When a message is received, the sender can prove that
the alleged receiver in fact received the message
25. Availability service
• Availability
• The property of a system or a system resource being
accessible and usable upon demand by an authorized
system entity, according to performance specifications for
the system
• Availability service
• One that protects a system to ensure its availability
• Addresses the security concerns raised by denial-of-
service attacks
• Depends on proper management and control of system
resources
29. Unwanted Access
• Placement in a computer
system of logic that exploits
vulnerabilities in the system
and that can affect
application programs as well
as utility programs
Programs can present
two kinds of threats:
Information access
threats
Intercept or modify
data on behalf of users
who should not have
access to that data
Service threats
Exploit service flaws in
computers to inhibit
use by legitimate users
