With all the snoops trying to get their hands on, well, every bit of information they can, encrypting sensitive content makes perfect sense. But there are various kinds of encryption you can use to protect yourself and your data, each with its pros and cons.

In this article, we will look at two types of encryption:

  • Disk encryption – The encryption of a Disk drive (or another storage device). To read any data on the disk, you need to know a password or a secret key.
  • Document encryption – The encryption of a complete document (or another file). To read the document, you need to know a password or a secret key.

We’ll take a quick look at how each type of encryption works, and talk about when you would want to use each type.

How To Encrypt Files With Disk Encryption?

Disk encryption works by encrypting part or all of a disk drive or other storage device. When you encrypt the entire disk, it is known as Full Disk Encryption (FDE). When only parts of the disk are encrypted, you have Encrypted Partitions on the disk.

FDE Basics

In a system using FDE, all the data on the disk is encrypted. When a user starts the system, they enter the encryption key, and the encryption software uses the key to encrypt/decrypt data on the fly.

Whenever data is read from the disk, it is decrypted before being used. Likewise, whenever data is written to disk, it is encrypted. Since the data on the disk is always encrypted, it is always inaccessible to anyone without the proper key, even if they physically take possession of the disk. And since the entire disk is encrypted, there is no way that sensitive data can find its way to an unencrypted file on the disk.

Encrypted Partition Basics

In a system using Encrypted Partitions, data automatically gets encrypted/decrypted only when it is stored on an Encrypted Partition. The user must take care to store documents and other files in the proper partitions.

The necessity to decide whether or not each file belongs on an Encrypted Partition means there is a chance that the user will make a mistake and leave sensitive data exposed. It is also possible for data stored in an Encrypted Partition to simultaneously appear in unencrypted form in a cache or swap file elsewhere on the disk.

Should I Encrypt My Disks?

In most cases, the answer is yes. You should encrypt your disks using FDE. It provides a basic level of protection with little or no performance impact once the disk is encrypted. Since the encryption is automatically applied to everything on the disk, you can’t forget to encrypt something, and the encrypted data can’t appear in an unencrypted file on the disk.

However, FDE does have some weaknesses. Perhaps most important, if the key is lost, the entire disk becomes unreadable. This makes the loss of the key much more damaging than when each document is encrypted individually with its own key. Some sort of key management system is almost mandatory to avoid eventual data loss.

Another weakness is that the system is vulnerable to hostile software while it is running. Reading and writing the encrypted disk is transparent to software once the disk is unlocked.
Finally, remember that FDE only protects files while they are stored on the encrypted disk. Sending a document to another computer by email, or even to an unencrypted disk on the same computer will leave the document unencrypted at its destination.

How To Encrypt Individual Files With Document Encryption

Document encryption (more properly file-level encryption) involves encrypting each document before it is saved. Ideally, every file will be encrypted with a unique key. This has several advantages over FDE or Encrypted Partitions.

Document encryption gives you fine control over who has access to which documents. Users only have access to the specific documents for which they have a key. On a system using FDE or Encrypted Partitions, a user with access to the disk or partition has access to every file on that disk or partition.

Encrypted documents remain encrypted when you email them or copy them to another disk. Only someone with the correct key can read an encrypted document, regardless of where it is located.

But the strength of document encryption is also a weakness. Anyone who needs to decrypt the document needs a copy of the key. Within an organization, distributing keys shouldn’t be a problem. Large companies and many small ones have Enterprise Content Management (ECM) Systems, Digital Asset Management Systems, or other tools that handle encryption and internal key distribution transparently.

But sending encrypted documents to external destinations can create a strange situation. While an encrypted document can be sent without worries, the key for decrypting it must be sent securely. Encrypting the key using PGP or some other Public-Key encryption system and the related Public Key Infrastructure (PKI) to send the key to the destination is one approach.

When Should I Encrypt My Documents And Other Files?

This is a hard one to answer. If you are in a corporate environment, this is all probably handled for you, or there are policies in place to tell you what to do.

On a personal level, you should ask yourself questions like these:

  • How good is my current network security?
  • How valuable is my data to outsiders?
  • How sensitive is the information in any particular document?
  • Is FDE sufficient, or do I need to take it further?
  • Will I be storing any sensitive documents online, sending them through email or social media, or storing them in the cloud?

While you will need to figure out an approach that is right for you, we have some general suggestions:

  • If a document contains sensitive information, and it will be leaving your computer or network, encrypt it.
  • If it is so sensitive that it could impact your career, your marriage, or your bank balance, encrypt it.
  • If you have reason to believe that you are being specifically targeted by someone or some government agency, encrypt it.
  • If it contains random information of little value or information that is already out on social media, you probably don’t need to bother encrypting it.

Beyond those suggestions, figuring out the right balance is up to you.

Increasing Your Privacy with a VPN or Tor

There is one last thing to consider before you decide on your document encryption policies. NSA documents released by Edward Snowden show that they consider anything that is encrypted to be suspicious. They can keep copies of any encrypted document as long as they like.

This reasonably raises the concern that sending an encrypted document somewhere simply paints a target on your back for the spies. While we aren’t sure whether that is true or not, there is something you can do to reduce your risks: use a VPN or Tor when sending encrypted documents anywhere.

While neither type of tool provides perfect protection, both VPNs and Tor encrypt all data passing to and from your computer. Because anyone monitoring the connection between your computer and the Internet can see only encrypted data passing back and forth, they have no way to tell you are transmitting encrypted documents as well. NordVPN is worth looking into, should you decide to start using a VPN.

Should I use disk and document encryption together?

Here is a quick summary of the main strengths and weaknesses of disk encryption (FDE) and document encryption:

FDE Document Encryption
Protects all data stored on a disk automatically Yes No
Protects data that leaves your computer or network No Yes
Result if key lost Entire disk inaccessible Specific document inaccessible
Vulnerable if an attacker has access to the computer while it is running Yes It depends on how document keys are distributed or managed.

Computer security experts recommend using disk encryption and document encryption together. By using FDE and document encryption together, you are creating a defense in depth. Using both types of encryption takes advantage of the strengths of each approach while minimizing some of their weaknesses.

An attacker would need to get past your disk encryption to even see that you have an encrypted document on the disk. Then the attacker would have to get past the document encryption to actually read any sensitive data.

SEC Chairman Says Crypto Markets Need Regulations to Prevent Fraud

Avatar

Published

on

SEC chairman Gary Gensler said on Friday that greater protection for investors is required in cryptocurrency markets. 

Gensler is no stranger to the cryptocurrency world. The former Goldman Sachs investment banker has long been viewed as a strong candidate to take the SEC chairman role.  

Gensler was sworn in a few weeks ago as Joe Biden’s choice for the next head of the SEC. During Obama’s presidency, Gensler was in charge of the Commodity Futures Trading Commission (CFTC) and was in charge of regulating derivatives.

What makes this particularly interesting is that he will become the first crypto and blockchain expert to hold the highly regarded position. A former MIT professor, he taught a course entitled “Blockchain and Money” and believes the two are a “catalyst for change.” Gensler stated at his SEC nomination hearing:

Bitcoin and other cryptocurrencies have brought new thinking to payments and financial inclusion. But they’ve also raised new issues of investor protection that we still need to attend to.”

Despite his support and optimism, the new SEC chairman also expressed concern about the protections investors are not getting in the crypto asset market. Gensler understands the attraction of bitcoin and other coins, but worries investors are taking on more risk than necessary

“It’s a digital, scarce store of value, but highly volatile,” Gensler says. “And there’s investors that want to trade that, and trade that for its volatility, in some cases just because it is lower correlation with other markets. I think that we need greater investor protection there.”

He believes that as long as technology continues to change the way consumers interact with markets, regulations to protect said consumers have to keep pace. 

He went on to say that he believes BTC is a “speculative” store of value and that the Securities and Exchange Commission should remain “tech neutral” when looking at innovations in markets. 

The new chairman believes there needs to be an official authority for a regulator to oversee digital currency exchanges.

The Magnificent Seven: TEL, ETC, QTUM, DOGE, OMG, EOS, LSK — Biggest Gainers, April 30 – May 7

Avatar

Published

on

BeInCrypto looks at the seven altcoins that increased the most over the past seven days, from April 30 to May 7.

These altcoins are:

  • Telcoin (TEL) – 420%
  • Ethereum Classic (ETC) – 295%
  • Qtum (QTUM) – 118%
  • Dogecoin (DOGE) – 100%
  • OMG Network (OMG) – 99%
  • EOS (EOS) – 90%
  • Lisk (LSK) – 74%

TEL

TEL has been moving upwards since April 23. In a span of 13 days, it increased by 1,000%, leading to an all-time high price $0.049. Since then, the token has decreased slightly.

TEL has already moved above the 1.61 Fib projection of waves 1-3, indicating that wave five has extended.

If it decreases, the closest support levels are found at $0.026 and $0.021, respectively. They are created by the 0.5 and 0.618 Fib retracement levels.

ETC

ETC began a massive upward movement on May 3, culminating with an all-time high price of $176, reached on May 6. This amounted to an upward movement of 292%.

The high was made right at the 3.61 external Fib retracement of the entire previous decrease, measuring from the all-time high. Afterwards, ETC decreased slightly since and is currently trading at $139.

If the current upward movement extends, the next resistance area would be found at $207, the 4.61 external Fib retracement.

QTUM

QTUM has increased considerably this week. However, unlike TEL & ETC, it is nowhere close to reaching its all-time high. 

To the contrary, it is still below the $43-$53 resistance area, which is created by the 0.5 – 0.618 Fib retracement levels. 

While QTUM is likely to reach it, a rejection would be expected once it does, at least in the short-term.

DOGE

DOGE has been moving upwards since April 23, when it had reached a low of $0.159. As a result, it managed to reach a new all-time high price of $0.696 on May 5, which amounted to an increase of 336%.

The high was made just above at the 1.61 external Fib retracement resistance, found at $0.627, causing a rejection. 

However, DOGE bounced once more after the rejection. 

If the movement extends, there is a confluence of resistance levels found near $0.90.

OMG

OMG has increased considerably this week, managing to reach a new yearly high of $15.35. Still, unlike ETC, the token is nowhere close to reaching a new all-time high. 

To the contrary, it has just reached the 0.5 Fib retracement level when measuring from the entire downward movement. Consequently, the entire $14.40-$17.75 area is likely to provide strong resistance.

Afterwards, if OMG manages to clear it, it is likely to move towards a new all-time high price.

EOS

EOS increased considerably this week, managing to break out above the long-term resistance area found at $8. Previously, it had been trading below this level since August 2019. 

As a result, it has managed to reach a high of $13.65, just between the 0.5-0.618 Fib retracement levels. However, it was rejected once it did, and is currently trading near $11.

LSK

LSK has been moving upwards since April 23, when it was trading at a low of $3.14. Today, it managed to reach a new all-time high price of $11.50, amounting to an increase of 271%. 

The high was made just above the 1.61 external Fib retracement level of the previous drop. This is the first significant resistance level.

Therefore, if LSK manages to clear it, the next resistance area would be found at $14.57.

Digital Currencies to Be Part of the Future, Says CEO of Rockefeller Capital Management

Avatar

Published

on

With the popularity of digital currencies on the rise, a number of business entities are searching for ways to enter the spade themselves. 

Bitcoin (BTC) continues to stand alone atop the mountain that is a cryptocurrency, for now. Other coins such as ethereum (ETH) have captured the attention of investors after a sharp spike in price.

Even the meme crypto dogecoin (DOGE) has been gaining a lot of traction lately. DOGE recently hit new highs right around the time that Elon Musk began trending due to an upcoming SNL appearance.  

Businesses getting involved

Not only are businesses getting involved, but U.S.-based banks are also clamoring to break into the cryptocurrency world. Reports suggest that these banks will soon allow clients to connect with digital currency lenders.  

Wall Street has already made the move after news broke this week of the S&P Dow Jones Indexes launching three new indices that are designed to track the performance of cryptocurrencies. In the meantime, major payment processors like Mastercard and Visa have started to accept crypto. 

A number of Wall Street firms such as JPMorgan will soon provide investors with bitcoin funds, while Goldman Sachs has launched bitcoin derivatives for investors. Meanwhile, Morgan Stanley will offer high-end clients a trio of bitcoin funds to work with. 

Despite this, some wealth management firms are not entirely convinced of the viability of crypto.

Not ready to offer crypto just yet

At a recent Bloomberg Wealth Summit meeting, both Gregory J. Fleming, CEO of Rockefeller Capital Management, and Sarah Levy, Betterment’s CEO, were questioned about the future of digital currency within the industry. 

“Our view on the whole crypto and digital currency space is that this is a change that is in the early stages, and you see that in the volatility around the price of the different ways of participating in this,” stated Fleming. “It is probably something that is more secular in nature, though. Digital currencies are going to be part of the future.”

Levy was also cautious, but, optimistic about the future of cryptocurrencies. 

“I think we’re in early innings on crypto. I think we’re believers that if we can provide the right kind of context and advice that it’s okay to participate in some of these newer asset classes. And so I’d like us to find a way to responsibly offer crypto but I can’t say that we’re there yet. I think we’re still in kind of watch and learn mode right now.”

While both CEOs are well aware of their client’s desire for investing in digital currencies, they are making the move slowly with a great amount of caution. Neither Levy nor Fleming is ready to offer crypto just yet. 

Despite the CEOs reticence to bring their companies into the crypto game, they both appear to be proponents of the industry itself. Fleming has shown a great amount of optimism surrounding digital currencies, even calling them a “game-changer”

Dogecoin Craze Outpacing Other Coins, Even Companies

Avatar

Published

on

Dogecoin (DOGE) has increased in value so rapidly, it has outpaced both bitcoin (BTC) and ethereum (ETH) by magnitudes, as well as large financial institutions.

For a cryptocurrency originally created as a joke, dogecoin has exceeded all expectations. But as recently as January of this year, dogecoin was trading for just a fraction of a penny. In February, the price rose significantly to over $0.05.

However, dogecoin really took off in April, increasing in value eight-fold to $0.40, before retracing. References from stalwart fans Mark Cuban and Elon Musk then gave it another boost. Thus far, dogecoin reached an all-time high of $0.65 on May 6.

Outshining bitcoin

Its rapid ascent has now seen it surpass gains of other notable cryptocurrencies and even companies. For instance, as monumental as bitcoin’s rise has been, in the past year its price has only risen over 500%. Even greater still has been Ethereum price gain, at over 1,600%. Meanwhile, dogecoin towers over both with an outrageous return of over $24,000, according to CoinGecko. 

The comparative gains were put into perspective by a recent tweet from personal finance blogger Nick Maggiulli. “Putting all three U.S. stimulus checks into dogecoin now exceeds $500,000,” he tweeted.

Conversely, if stimulus check recipients put their cash into bitcoin it would be worth around $15,000. Recently, a survey found around 10% of stimulus check funds may have been used to buy crypto and stocks. This amounts to nearly $40 billion of the $380 billion in direct stimulus check deposits.

Explosive demand

Even in the past week, dogecoin has essentially doubled in value. Earlier BIC reported that being valued at $49.8 billion meant it was valued higher than the Ford Motor Company ($45.2 billion) and social media giant, Twitter ($44.1 billion).

At that point it ranked at #255 on the Asset Dash rankings. Now, less than a week later, the coin jumped nearly 100 places to #156, with a valuation over $80 billion. It has now surpassed financial conglomerate CME Group (#175) and crypto exchange Coinbase (#193).

Demand for dogecoin is so outrageous, it reportedly even single-handedly crashed several exchanges. On April 16, mobile exchange Robinhood crashed just as trading volumes for dogecoin were spiking. The largest crypto exchange in India also struggled to keep pace with demand for dogecoin.

WazirX’s systems denied access to many users because they incorrectly perceived the surging volumes as a cyberattack. Meanwhile, other exchanges are scrambling to offer the digital asset, such as trading platform eToro and cryptocurrency exchange Gemini.
