Cell Site Analysis
(CSA) is one of the single most important processes in
determining the actual operational footprint and
physical/geographic movements of a mobile
telephone. |
Whilst mobile
devices such as telephones can hold only
a relatively small amount of data when
compared to desktop computers,
information relating to physical
movement
can be extremely valuable and revealing.
This process involves engineers carrying out
comprehensive drive trials around a
specific route or focussing their
attention on a single Post Code.
These drive trials measure actual cell
site coverage utilising the most
sophisticated data gathering, global
positioning and analytical tools in the
industry.
The gathered information is used as the
basis for producing detailed coverage
maps where the total area
driven is demonstrated and the coverage
areas of the individual cell sites are
shown as different colours. Maps are
available in many formats including
aerial photography, OS ranges and A-Z streetmaps.
Our service includes the post-analysis
review of investigation results and the
preparation of a detailed investigation
report. The appointed forensic analyst
will review the telecommunications
infrastructure and determine whether the
prosecution findings are indeed accurate
and where the best avenues of challenge
for the defence case reside.
From
the identification of anomalies, such as
network 'black-spots', presence of
'repeaters', areas of 'non-dominance',
and other factors can be explored and
used to asist in undermining police
evidence and the reliability of the
investigation.
Analysis of the Call Detail Records can
also indicate association of individual
handset numbers, geographical location
of handset utilisation i.e. post codes
and addresses of individual cell sites,
specific handset and SIM card pairings,
incoming and outgoing calls and date,
time and duration of calls.
Our service includes the post-analysis
review of investigation results and the
preparation of a detailed investigation
report. If criminal or other legal
proceedings are necessary we can produce
witness statements and attend court to
deliver expert testimony in support of
the analysis undertaken and material
found.
We offer a 24x7 comprehensive
investigation service that involves the
recovery of digital information. Our
experts work with clients to determine
the nature of incidents and use
established computer forensic
investigation techniques to preserve
evidence, whilst maintaining its
continuity and integrity. Our analysts
are Certified Information Security
Professionals (CISSPs) and trusted to
undertake the most sensitive of
investigations.

Understanding Encryption
Encryption is the process of
transforming information (referred to as plaintext) to
make it unreadable to anyone except those possessing
special knowledge, usually referred to as a key. The
result of the process is encrypted information (in
cryptography, referred to as ciphertext).
In many
contexts, the word encryption also implicitly refers to
the reverse process, decryption (e.g. "software for
encryption" can typically also perform decryption), to
make the encrypted information readable again (i.e. to
make it unencrypted).
Encryption has long been used by militaries and
governments to facilitate secret communication.
Encryption is now used in protecting information within
many kinds of civilian systems, such as computers,
networks (e.g. the Internet e-commerce), mobile
telephones, and bank automatic teller machines.
Provisions
in Part III of the 'Regulation of Investigatory Powers
Act 2000' provide law enforcement authorities with
the right to demand access to the original plaintext or
encryption keys, so as to prevent crime or assist in
ongoing investigations.
Whether passwords or encryption keys have been lost,
forgotten, or rendered unusable due to corruption -
BURTON DIGITAL have unique facilities to assist clients
in unlocking protected data to
assist in defence case preperations. |
