Security FAQ and Tips
The following is a list of frequently asked questions and their answers, but feel free to ask us anything else you want to know.
1. What is encryption?
Encryption is the scrambling of data into a secret code that cannot be
deciphered except by the intended party. Given enough time (and enough
computing power) allencrypted messages can be read but this can take
massive amounts of time and resources.
In simple terms, encryption is a way for you to secure your files and
your e-mail from spying eyes. Your files get translated into code that
makes no sense to anyone who sees it. It is an apparently random
collection of numbers and letters. To encrypt a file, you "lock" it
with a key, represented by a passphrase. To encrypt a message, you lock
it with a key pair using your passphrase. It can only be opened by the
intended recipient, who uses his or her own passphrase.
2. Why should human rights groups use encryption?
Everyone should use encryption because digital communications are
inherently unsafe. However, human rights workers are at a far greater
risk than most individuals and their files and communications are more
sensitive. It is imperative for human rights workers to use encryption
in their digital communications to protect themselves and the people
they are trying to help.
Digital technology is a benefit to human rights groups, allowing them
easier communications, greater efficiency and more opportunities.
However, with any benefit come certain dangers. You wouldn't drive a
car without seatbelts even if you were not likely to get into an
accident every time you drive. If you are driving in a more dangerous
situation such as a race, you are more likely to use the available
tools to make you safer.
Similarly, human rights workers are known targets for surveillance.
Knowing unencrypted email can be viewed by almost anyone from many
different points of access makes it almost inevitable that their
unencrypted email will be accessed at some point. Your messages may
already be monitored by your adversaries and you will never know about
it. Your beneficiaries' adversaries are your adversaries.
3. Is it illegal to use encryption?
Sometimes. It is perfectly legal to use encryption in the United
States, Canada and other western nations including Peru. In fact it is
legal in most countries of the world. However, there are particular
exceptions in other parts of the world. In China, for example,
organizations must apply for a permit to use encryption and everyone
must report any encryption technology on their laptops as they enter
the country. Singapore and Malaysia have laws requiring anyone wishing
to use encryption to report their private keys. Similar laws are
pending in India. There are other exceptions as well.
The Electronic Privacy Information Center (EPIC) provides An
International Survey of Encryption Policy where they discuss the laws
in most countries http://www2.epic.org/reports/crypto2000/, however this list was last updated in 2000. Before you use encryption in a particular country, check with us.
4. What software is available?
There's email encryption, disk encryption, anonymous remailers, backup systems, virus protection, firewalls, and more!
But having the right software is not the whole solution. The weakest
link is usually individuals, not technology. Encryption doesn't work if
individuals don't use it consistently, if they share their passphrases
indiscriminately or leave them in visible locations such as a sticky
note pasted to their monitors. Backup software won't save you in the
event of a fire or raid if you don't ensure the backup copy is stored
at a separate secure location. Sensitive information must be treated on
a need-to-know basis instead of being shared with everyone in
organization, so you need to initiate hierarchies and protocols. In
general, it's important to have a consciousness of privacy and security
in your everyday activities. We call this "healthy paranoia".
5. What do we need?
It depends on your system and your activities, but generally everyone should have:
- A firewall
- Disk encryption
- Email encryption that also does digital signatures such as PGP
- Virus detection software
- Secure backup email to a secure site and backup all materials weekly to CD-RW then store it at a separate secure location
- Passphrases that can be remembered but can't be guessed
- A hierarchy for access everyone in the organization does not need access to all files
- Consistency none of the tools will work if you don't use them all the time!
6. How do you choose which encryption software to use?
Usually, you ask your friends &and confirm with us. You need to
communicate with certain people and groups so, if they are using a
specific encryption system, you should use the same system to
facilitate communications. However, check with us first. Some software
packages simply don't do a good job while others are Honey Pots. With a
honey pot, you are lured into using the free and seemingly excellent
software by the very people who want to spy upon you. How better to
read your most vulnerable communications than by being the overseer of
your encryption software? Still, there are many reputable brands of
both proprietary software and freeware. Just remember to investigate
before you use it.
7. Won't using encryption put me at a greater risk of a crackdown?
No one will know you are using encryption unless your email traffic is
already being watched. If your email traffic is already being watched
then your private information is already being read. That means you are
already involved in a crackdown by those doing surveillance on you.
There is a concern that those doing surveillance on you will use other
options if they can no longer read your email, so it is important to
know your co-workers, implement safe backup policies and consistent
office management at the same time you begin to use encryption.
8. Why do we need to encrypt email and documents all the time?
If you only use encryption for delicate matters, those watching you or
your clients can infer when critical activity is taking place &and are
likely to crack down at those times. While they cannot read your
encrypted communications, they can tell whether files are encrypted or
not. A sudden rise in encryption may trigger a raid so start using
encryption before special projects arise. In fact, it's best to ensure
all communication traffic flows smoothly. Send encrypted email at
regular intervals, even when there is nothing new to report. This way,
when you need to send delicate information, it will be less noticeable.
9. If I've got a firewall, why do I need to encrypt my email?
Firewalls prevent hackers from accessing your hard drive and network
but, once you send an email out into the Internet, it's open to the
world. You need to protect it before you send it.
10. No one is breaking into this office so why do I need to use privacy software?
First, you don't know if anyone is breaking into your system or if
anyone is leaking information. Without encrypted communications,
without physical security, without privacy protocols, anyone can be
accessing your files, reading your e-mail and manipulating your
documents without your knowledge. Second, your open communications can
put others at risk in locations where politically motivated raids are
more likely to occur. If you lock your doors, you should encrypt your
files. It's that simple.
11. We don't have Internet access so we have to use an Internet
café. How can we protect communications that we send from an outside
computer?
You can still encrypt your email and your files. Before going to the
Internet café, encrypt any files you intend to email and copy them in
encrypted form onto your floppy disk or CD. At the Internet café, sign
up for an encryption service such as Hushmail.com or an anonymity
service such as Anonymizer.com, and use these when sending your email.
Make sure the people receiving your communications have already signed
up for these services.
12. If it's so important to secure our files and communications, why doesn't everyone do it?
This technology is relatively new but its usage is spreading. Banks,
multinational corporations, news agencies and governments all use
encryption, recognizing it to be a sound investment and a necessary
cost of doing business. NGOs are at greater risk than companies whom
most governments wish to welcome. NGOs are more likely to be targeted
for surveillance so they need to be proactive in implementing the
technology. The focus for human rights workers is protecting persecuted
individuals and groups. To do so, they keep files with identifying and
locating information. If these files are accessed, these individuals
can be killed, tortured, kidnapped, or "convinced" not to assist the
NGO anymore. Information from these files can also be used as evidence
against the NGO and their clients in political prosecutions.
13.
One of our principles is openness. We are lobbying for greater
transparency by the government. How can we use privacy technology?
Privacy is consistent with openness. If the government wishes to openly
request your files, it can do so through proper and recognized
procedures. Privacy technology stops people from accessing your
information in a clandestine manner.
14. We follow all the privacy and security protocols and still our information is leaked what's going on?
You may have a spy within your organization or you may have someone
that simply cannot keep information confidential. Rework your
information hierarchy to ensure fewer people have access to delicate
information and keep an especially watchful eye on those few people.
Large corporations and organizations routinely disseminate different
bits of false information to specific people as a matter or course. If
this false information leaks out, the leak can be tracked directly back
to the employee who were told the original (false) information.
The Do's and Don'ts of Using Encryption
- DO use encryption consistently. If you only encrypt sensitive
material, then anyone monitoring your email traffic will know when
something important is about to happen. A sudden increase in use of
encryption might lead to a raid.
- DON'T put sensitive material in subject lines. They are usually not encrypted even if the message is.
- DO use a passphrase containing letters, numbers, spacing and
punctuation that only you can remember. Some techniques for safe
passphrase creation are using designs on your keyboard or using random
words strung together with symbols in between. In general, the longer
the passphrase, the stronger it is.
- DON'T use a single word, name, popular phrase or an address
in your address book for your passphrase. These can be cracked in
minutes.
- DO backup your private key in a single secure place, such as
encrypted on a tiny, removable "keychain" USB memory device or a Sony
memory stick.
- DON'T reply with sensitive materials to someone just because
they send an encrypted email and use a recognizable name. Anyone can
"spoof" a name by making his or her email address sound like someone
you know. Always verify an identity before you choose to trust the
source communicate in person, by phone or by checking their digital
fingerprint with a reliable source.
- DO teach others to use encryption. The more people using it, the safer we will all be.
- DON'T forget to sign the message as well as encrypting. You
want your recipient to know whether your message has been altered in
transit.
- DO encrypt files that you send as attachments separately.
They are generally not encrypted automatically when you send an
encrypted email.
