- Proper Disposal of Electronic Devices - Why is it important to
dispose of electronic devices safely? - In addition to effectively
securing sensitive information on electronic devices, it is
important to follow best practices for electronic device disposal.
Computers, smartphones, and cameras allow you to keep a great deal
of information at your fingertips, but when you dispose of, donate,
or recycle a device you may inadvertently disclose sensitive
information which could be exploited by cyber criminals.

Catching all Threats – Known, Unknown, and Unknown Unknown - Before
They Can Harm You - At a news briefing in 2002, when then U.S.
Secretary of Defense Donald Rumsfeld, famously broke down threats
into three categories of “knowability”: “Known knowns,” are the
threats we are fully aware of; “known unknowns,” are the things we
know we don’t know; and finally, the “unknown unknowns” – those
threats that we don’t even know we don’t know.

5 steps for securing connected medical devices - Patients expect
hospitals to be safe havens, but more and more we’re seeing that the
weakest and most critical assets in hospital networks are the very
instruments needed to save lives: medical devices. With the increase

WEB SITE COMPLIANCE -
We continue our review of the FDIC
paper "Risk Assessment Tools and Practices or Information System
Security."
RISK ASSESSMENT/MANAGEMENT
A thorough and proactive risk assessment is the first step in
establishing a sound security program. This is the ongoing process
of evaluating threats and vulnerabilities, and establishing an
appropriate risk management program to mitigate potential monetary
losses and harm to an institution's reputation. Threats have the
potential to harm an institution, while vulnerabilities are
weaknesses that can be exploited.
The extent of the information security program should be
commensurate with the degree of risk associated with the
institution's systems, networks, and information assets. For
example, compared to an information-only Web site, institutions
offering transactional Internet banking activities are exposed to
greater risks. Further, real-time funds transfers generally pose
greater risks than delayed or batch-processed transactions because
the items are processed immediately. The extent to which an
institution contracts with third-party vendors will also affect the
nature of the risk assessment program.

SECURITY
CONTROLS - IMPLEMENTATION
LOGICAL AND ADMINISTRATIVE ACCESS CONTROL
Access Rights Administration (4 of 5)
The access rights process programs the system to
allow the users only the access rights they were granted. Since
access rights do not automatically expire or update, periodic
updating and review of access rights on the system is necessary.
Updating should occur when an individual's business needs for system
use changes. Many job changes can result in an expansion or
reduction of access rights. Job events that would trigger a removal
of access rights include transfers, resignations, and terminations.
Institutions should take particular care to remove promptly the
access rights for users who have remote access privileges, and those
who administer the institution's systems.
Because updating may not always be accurate, periodic review of
user accounts is a good control to test whether the access right
removal processes are functioning, and whether users exist who
should have their rights rescinded or reduced. Financial
institutions should review access rights on a schedule commensurate
with risk.
Access rights to new software and hardware present a unique
problem. Typically, hardware and software are installed with default
users, with at least one default user having full access rights.
Easily obtainable lists of popular software exist that identify the
default users and passwords, enabling anyone with access to the
system to obtain the default user's access. Default user accounts
should either be disabled, or the authentication to the account
should be changed. Additionally, access to these default accounts
should be monitored more closely than other accounts.
Sometimes software installs with a default account that allows
anonymous access. Anonymous access is appropriate, for instance,
where the general public accesses an informational web server.
Systems that allow access to or store sensitive information,
including customer information, should be protected against
anonymous access.

Chapter 18 - AUDIT TRAILS
18.1 Benefits and Objectives
18.1.2 Reconstruction of Events
Audit trails can also be used to reconstruct events after a problem
has occurred. Damage can be more easily assessed by reviewing audit
trails of system activity to pinpoint how, when, and why normal
operations ceased. Audit trail analysis can often distinguish
between operator-induced errors (during which the system may have
performed exactly as instructed) or system-created errors (e.g.,
arising from a poorly tested piece of replacement code). If, for
example, a system fails or the integrity of a file (either program
or data) is questioned, an analysis of the audit trail can
reconstruct the series of steps taken by the system, the users, and
the application. Knowledge of the conditions that existed at the
time of, for example, a system crash, can be useful in avoiding
future outages. Additionally, if a technical problem occurs (e.g.,
the corruption of a data file) audit trails can aid in the recovery
process (e.g., by using the record of changes made to reconstruct
the file).
18.1.3 Intrusion Detection
Intrusion detection refers to the process of identifying
attempts to penetrate a system and gain unauthorized access.
If audit trails have been designed and implemented to record
appropriate information, they can assist in intrusion detection.
Although normally thought of as a real-time effort, intrusions can
be detected in real time, by examining audit records as they are
created (or through the use of other kinds of warning
flags/notices), or after the fact (e.g., by examining audit records
in a batch process).
Real-time intrusion detection is primarily aimed at outsiders
attempting to gain unauthorized access to the system. It may also be
used to detect changes in the system's performance indicative of,
for example, a virus or worm attack. There may be difficulties in
implementing real-time auditing, including unacceptable system
performance.
After-the-fact identification may indicate that unauthorized access
was attempted (or was successful). Attention can then be given to
damage assessment or reviewing controls that were attacked. |
