2. CYBER SECURITY – PRESENT MALAISE
1. All the problems with cyber security in the
world due to
2. Catching the bull by the tail and running
after it.
3. We let all the muck in and then try and
detect and clean it.
3. THE SOLUTION
4. The only way to ensure 100% security of
an organisation’s internal databases and
WAN computing is
a. To catch the bull by the horns and lock it
out of the internal network.
b. In other words isolate the INTRANET
from any public domain access at LAN /
MAN / WAN levels.
c. MAN / WAN isolation shown in PVDTN
WAN sketches of Figs. 1 and 2.
d. Fig. 3 shows the separation at LAN level

CS – Company Communications Server
PS – Company Web or Public Server
IS – Intermediate Server which relays

Between CS & PS.
SSA – Automatic Secure Switch which
connects IS to INTRANET and Internet
LAN buses alternately in preset
(adjustable) time.
DB1, DB2 – Company’s internal

6. ORGANISATIONS PRESENCE ON INTERNET
5. All organisations need presence on the Internet.
6. For this STS (secure transfer system)
developed and patented.
7. For free flow of information / data / mail
back and forth between the Internet and the
INTRANET, automatically.
8. Without impairing the security of the
INTRANET.
7. STS (SECURE TRANSFER SYSTEM)
9. The STS comprises of
a. Company communications server (CS)
connected to the INTRANET LAN
b. The Company Web Server or public server
(PS) connected to the Internet LAN
c. The Intermediate or relay server (IS)
connected to the secure switch (SS).
d. The SS is a 3 position, electro-mechanical,
microprocessor driven, RJ 45 switch which
connects the IS either to the INTRANET or
Internet alternately.
e. Never to both together.
f. Switch cycle periodicity may be set from
500 milli seconds upwards.
g. SS designed developed and manufactured
for MIDAUTEL exclusively.
h. Covered by STS letter of patent 262590.
8. EXCHANGE OF INFORMATION / DATA / MAIL
BETWEEN INTRANET & INTERNET
10. Information / data / mail transferred
between two networks by alternate two-way
synch between IS and CS, and IS and PS
11. All computer nodes in INTRANET LAN
receive and send internal and external from
and to the Company mail server (CMS).
12. External mail is routed via the STS and the
Internet mail gateway (IMG) residing in the
PS.
9. INTERNET BROWSING NODEs (IBNs)
13. Employees who need to browse the
Internet are provided with Internet Browsing
Nodes IBNs) comprising
a. A switchable thin client with on-demand
switching software embedded with the thin
OS
b. A SS (secure switch) operated by the on-
demand switching software.
c. Two VMs, one in the VDS (virtual desktop
server) connected to the INTRANET LAN
and one in the VDS connected to the
Internet LAN.
d. IBN users will work with the VMs on the
INTRANET and Internet LANs.
e. Hence two networks are kept separate.
f. Obviates internal (mole) threats.
g. See Fig. 3
10. ACCESS BY FIELD OFFICERS
FROM MOBILE PHONES
1. The Company Web site will have two types of
pages
a. Read only - accessible to people in the
public domain for all the publishable
information they carry.
b. Interactive – accessible to those with
registered email IDs and passwords, and with
registered mobile numbers which will receive
OTP for access
c. The field officers will have to leave their
inputs on these interactive pages for onward
transmission to the internal network via the
STS system. They will not get direct access
to the internal network from the field but via
the Web server connected top the Internet.
d. The answers they want from the Company
will either be relayed to the interactive pages
or via mail in the registered email ID.
11. PROTECTION AGAINST MALWARE
SENT VIA EMAIL
1. Any one can send a mail to the Company mail
ID containing malware.
2. To protect against this the IS (intermediate or
relay server) is provided with anti-Malware
software in addition with the anti-virus
software.
3. The former displays the registry files and the
CISO / and his team will be on constant watch
for any suspicious files which would be
promptly deleted.
4. IS – the only route via which such malware can
get into the network during the two-way synch
with PS and CS in the STS system.
5. Malware detected and eliminated with the help
of the anti-malware software.
6. This activity of CISO / team restricted to
Central location of the organisation or at best
also in the DR (disaster recovery) site which
will also have a STS system.
12. DEMONSTRATION OF CUSTOMISABLE
STS EXCHANGE SOFTWARE
1. The STS exchange software depends on
specific needs of each organisation and is
custom built.
2. This can be demonstrated at the
Organisation’s premises in a parallel demo
site after getting the inputs from the CIO /
team.
3. We will need three servers (CS, IS, PS) of
appropriate size to suit the need of the
organisation, and also a Secure Switch (SS).
4. To demo the typical IBN function we will
need two high end PCs to act as the VDSs at
the INTRANET and Internet LAN switches,
each with two VMs (virtual machines), and
two switchable thin clients each comprising
a. One SS
b. One switchable thin client with on-
demand switching software
embedded with the thin OS
5. The customised software developer will roll
out the working model on successful
completion of the demo.
6. The Organisation will be free to employ
ethical hackers to hack through the STS
system.
13. BENEFITS TO USERS
1. Ensures 100% security of internal databases,
and WAN computing
2. Saves 50 to 75% of present telecom costs
3. Saves a substantial portion of inter-locational
travelling costs through multiple simultaneous
NET meetings for different work groups with
people from their own work places at a
moment’s notice, using
a. Voice conferencing
b. Voice-data conferencing
4. Smartens up company operations
5. The cost of re-engineering the present network
can be recovered from the savings in telecom
and travelling costs in 1 to 3 years. The more
the communications the quicker the payback.
6. There is also an immeasurable saving from
ensuring 100% security of internal databases
and WAN computing – which could run into
Crores INR – by ensuring the Company /
Organisation functions without any data
breaches
