Why choose a career in Digital marketing?
What is digital marketing?
In some ways, digital marketing is not that different from traditional marketing: you’ve got a product that you need to sell, and you’re looking to ways to engage with customers to build brand awareness and eventually “close” a sale.
Digital marketing encompasses, even more, roles and skills than marketing ever before, and it’s this flexible, versatile nature of the business that makes it so fascinating. Here are some general areas that a digital marketing professional will likely touch on during their training or career:
- Video/audio production
- Interactive technology (such as AI)
- Mobile marketing
- Search engine optimization (SEO)
- Search engine marketing (SEM)
- Social media
- E-commerce
- Email marketing
- Marketing automation
- Content management and curation
- Web development
- Web design
- Copywriting and editing
- Analytics
- Business/marketing strategy
It’s a good idea to think about getting training in at least one or two specialty areas, unless you’re in management, in which case you’ll probably need to know quite a bit about them all.
What skills are in demand?
The digital economy is embedded in every corner of our lives, and it’s definitely not going anywhere. There’s a solid budget going into digital marketing now as opposed to the traditional marketing. 93% of online activity starts with a search engine, and ensures the continued effectiveness of SEO as a superior marketing strategy while about 80% of Americans make an online purchase at least once a month. Anyone thinking about starting or leading a business needs to have a basic understanding of digital marketing in order to convert customers.
There is plenty of room for people looking to enter the world of digital marketing and related careers. According to Smart Insights, some of the most in-demand skills for 2017 were digital advertising, content creation, content strategy, and social media, which is great news for those who veer towards the creative, social and business end of the spectrum.
For those who are more technically minded, there’s still plenty of demand and quite a high earning potential for those who specialize in technology like SEO and SEM since this is what can be at the base of what drives profits in any business. Content marketing relies on traffic and anyone with the technical expertise to analyze these patterns is going to be a valuable asset, especially as these types of jobs become more complex with the advent of AI.
Why choose a career in digital marketing?
Digital marketing is a career that has plenty of room for techs, creatives, and business people. There are so many avenues that you can follow; it’s best to focus on one or two things that you do best, then you can always learn more from there. If you have a business or communications background, you may want to consider going into management.
This is a field that’s ever-changing and engaging; there’s always something new to learn. And if you work in an agency, you’ll always be working with different clients, which means you’ll probably never get bored.
Beyond this, here are a few more reasons to consider this career.
There’s a Digital Skills Gap: There’s a growing demand for people with digital skills, particularly for those in the middle-income bracket, specifically soft skills, and according to this study, it’s most pronounced in the US. So, sticking with ongoing training in this area, even if you’re not a complete tech geek, is a good thing to bank on into the foreseeable future.
Versatility: If you choose a career path or specialization in this field and you decide to pivot later, you’ll likely only need a little training in order to make the switch. In this sense, you can build on existing skills while still learning new ones but still stay in the same field. There’s plenty of choices, here, and ongoing learning opportunities, where different skills fit together in different ways.
The Industry is Always Evolving: As the industry grows and changes, there’s always something new and interesting to learn, and you can follow along and learn, whether you’re taking the lead on these initiatives or not. Since there will be a variety of specialists working in a given agency, you’ll likely be working alongside professionals with a variety of backgrounds, with everyone having to come together to build marketing strategies.
Earnings: When a job is in demand, that means there’s more opportunity to negotiate remuneration whether you are working in-house or as a freelancer. So long as you “show” your work through the job search process, you’ll be able to bid higher and higher the more experience you get. According to the Creative Group, content writers early in their career will likely start at a salary of at least $45, 000 and a new SEO specialist will probably be earning about $50,000 to start.
Be Creative: Not only is there plenty of opportunities for creatives to do their thing in writing, design and even video and audio production, there’s also plenty of room for day-to-day creativity in a general sense. You’ll always be having to think of new ways to market products, solve problems, and engage audiences.
Train at Your Own Pace: You can start working on building this specific career now, from the comfort of your own home, and do it your way. Take online courses, build a blog or a website, work on your own social media, get some volunteer or freelance work, and you’re on your way to building a solid portfolio from the comfort of your own home. For most specialties, there’s no need to spend thousands of hours and dollars sitting around in a classroom—you can really build your skills and get training in a way that suits your lifestyle.
Work with Different People Every Day: You’re always going to find something new to do in this field - and have someone new to talk to. Whether it’s a new client, a colleague with an interesting specialty, or finding fun ways to engage and expand your audience, anyone with an interest in working with people will do well in the social and business end of this career. And if you’re a little more on the introverted side, you can stay behind the scenes doing writing or web work.
What types of people excel in this field?
All sorts of people can follow a career that touches on marketing; it depends on what your interests are. Having an extremely technical background isn’t usually necessary, though if you do know a thing or two about web design or coding, you’re probably going to be ahead of the competition.
Because this is such a dynamic field that requires ongoing learning, you pretty much need to be a self-starter—that is, willing to teach yourself new skills and technology on an ongoing basis. To this end, you’ll need to be a creative problem-solver. If you are curious, innovative, proactive, a natural leader, adaptable, creative, and have a good business sense; you’ll probably do well in most areas in this field.
How do you get trained as a digital marketing professional?
If you already have a background in marketing management, copywriting, web development or even design, you’ve already got plenty of transferable skills to go into digital marketing. You’ll probably want to get started on your own personal branding and build a portfolio in order to build your own unique digital presence.
It’s tough to stay on top of all of the latest trends, but getting a solid understanding of the basics of up and coming trends like AI and virtual reality in the context of how they’re being used for marketing is an excellent place to put your focus as well.
You should certainly make sure that your social media streams are consistent with your skills and aptitude--in other words, talk about what you are interested in and learning about publicly and as often as you can. Start a blog over at Medium and join some Facebook groups in your field of interest.
You’ll want to also look for a comprehensive, reputable training program to get official certification in one or more core areas. Once you’re officially certified, you’ll then have a leg-up amongst your peers when it comes to searching for fulfilling opportunities.
Top 5 Programming Languages that may Dominate the Future
As we all are familiar by the fact that I.T (Information & Technology) is among the most dynamic industries in the world. How? It’s because every day we see lots of stuff and technological innovations going around us.
This makes it a very demanding and challenging field, where Developers had to really work hard and learn those newly trending programming languages so that they can keep themselves more updated and efficient.
In contrast to this One more interesting fact is that Programming is the Highest paying industries in the world. Wanna know more about it?
List of Top 5 Programming Languages that may have highest demand in the Future.
1. Kotlin
The first programming language in our list is Kotlin. The current hold of Kotlin on Android development clearly hinted its dominance over Android development.
This newly launched masterpiece had some powerful key features which made Java feel a bit outdated.
Kotlin is open source general purpose and object-oriented programming language which runs on JVM (Java Virtual Machine). It also proves to be very useful when you want to work on custom android apps. This also features easy coding, android studio support and much more.
Though Java is also a very powerful and preferred language for Android, but now by the introduction of this language, developers have shifted to Kotlin. There are many reasons behind this sudden shift, to know more about them.
2. Swift
A few years back Apple decided to launch a new language which could take over its predecessor (Objective C) for Ios development. And to our surprise, it did pretty well.
So If you are a fan of “Apple” then you must be familiar with this programming language. Why? mainly because it was used to develop apps for almost every Apple device. Devices such as iPhone, iMac, MacBook, or AppleTV and much more.
it has also been observed that from past couple of years, “Swift” was getting ranked in the list of top 10 programming languages. How? mainly because of its features and syntax.
Every Ios developer had a swift certification in his pocket. Not only because swift is popular but because swift has some features and functionalities which was not offered by other Ios specific languages.
Many experienced developers also stated that there will be no competition of Swift in upcoming years as well. Which makes it to be counted into the list of Programming Languages that may Dominate Future.
3. Python
Recently Python took over Java because of its simplicity and easy to go syntax. This language is so simple that even a 6-year old kid can code in it. It is also considered as one of the most popular object-oriented languages as it lets you focus more on the solution rather a problem itself.
Many experienced developers who were using C++ and Java have shifted to this language, as it offered them more reliability and a great set of code functionalities as well.
Well, there are some other reasons as well which made python more dominant than others such as
- its free and open source
- Highly-extensile and portable
- Also has a huge set of Standard libraries in it.
This clearly made Python to be counted in the list of top 10 programming languages in the world.
4. MATLAB
Developed by Mathworks this language is widely preferred for data science.
It integrates computation, visualization, and programming in an easy-to-use environment where problems and solutions are expressed in familiar mathematical notation.
The algorithms written in this language is considered as fast, stable and more powerful than others in terms of mathematical problems. Also used for statistical analysis which is performed by data scientists.
5. Rust
Rust is the most pampered language on the internet. This year according to the survey conducted by the Stack Overflow, Rust ranked the “Most Loved” programming language. This clearly signals that Rust is more popular than of its competitors such as Kotlin, java, and python.
The story behind this love was as clear as a mirror. Rust is open-source, safe, simple and has a concrete syntax as compared with legendary C and C++. The syntax is friendly to new developers who have little or almost no experience in programming. Widely used for web and operating system contexts.
Surprising Differences between TLS and SSL Protocol
TLS is simply a successor of SSL 3.0, TLS is a protocol which provides Data encryption and Integrity between communication channels. SSL 3.0 is served as a base for TLS 1.0.
SSL OR TLS Which is good?
We use to believe that TLS 1.0 is a Successor of SSL 3.0. As we know SSL3.0 are very old and recent attacks like POODLE, BEAST and other attack vectors made SSL3.0 lifeless as a security protocol.
Due to POODLE attack, SSL v3 is being completely disabled on web sites around the world.
Then the BEAST attack which completely break web sites running on older SSL v3.0 and TLS v1.0 protocols.
Sadly still some of the websites do not use TLS, you can check your website configuration using Comodo SSL analyzer.
TLS Handshake Protocol
When a TLS client and server first start communicating, they agree on a protocol version, select cryptographic algorithms, optionally authenticate each other, and use public-key encryption techniques to generate shared secrets.
The TLS Handshake Protocol involves the following steps:
- Exchange hello messages to agree on algorithms, exchange random
values, and check for session resumption. - Exchange the necessary cryptographic parameters to allow the
client and server to agree on a premaster secret. - Exchange certificates and cryptographic information to allow the
client and server to authenticate them. - Generate a master secret from the premaster secret and exchanged
random values. - Provide security parameters to the recording layer.
- Allow the client and server to verify that their peer has
calculated the same security parameters and that the handshake
occurred without tampering by an attacker.
TLS and SSL Protocol Notifications
If any problem’s encountered in the connection any one of the parties who discover the issue will trigger an alert message. You can find some cheap wildcard SSL certificates here.
SSL Alert Descriptions
Close_Notify
This message notifies the recipient that the sender will not send any more messages on this connection.
Unexpected_message
An inappropriate message was received. This alert is always fatal and should never be observed in communication between proper implementations.
Bad_record_mac
This alert is returned if a record is received with an incorrect MAC. This alert will be returned if an alert is sent because a TLSCiphertext decrypted in an invalid way: either it wasn’t an even multiple of the block length, or its padding values, when
checked, weren’t correct.

User_canceled
This handshake is being canceled for some reason unrelated to a protocol failure. If the user cancels an operation after the handshake is complete, just closing the connection by sending a close_notify is more appropriate. This alert should be followed by a close_notify. This message is generally a warning.

If the user cancels an operation after the handshake is complete, just closing the connection by sending a close_notify is more appropriate. This alert should be followed by a close_notify. This message is generally a warning.
No_renegotiation
Sent by the client in response to a hello request or by the server in response to a client hello after initial handshaking. Either of these would normally lead to renegotiation; when that is not appropriate, the recipient should respond with this alert. At that point, the original requester can decide whether to proceed with the connection.

Either of these would normally lead to renegotiation; when that is not appropriate, the recipient should respond with this alert. At that point, the original requester can decide whether to proceed with the connection.
One case where this would be appropriate is where a server has spawned a process to satisfy a request; the process might receive security parameters (key length, authentication, etc.) at startup, and it might be difficult to communicate changes to these parameters after that point. This message is always a warning.
Unsupported_extension
sent by clients that receive an extended server hello containing an extension that they did not put in the corresponding client hello. This message is always fatal.
sent by clients that receive an extended server hello containing an extension that they did not put in the corresponding client hello. This message is always fatal.
Compatibility with TLS and SSL
Since there are various versions of TLS (1.0, 1.1, 1.2, and any future versions) and SSL (2.0 and 3.0), means are needed to negotiate the specific protocol version to use. The TLS protocol provides a built-in mechanism for version negotiation so as not to bother other
protocol components with the complexities of version selection.
protocol components with the complexities of version selection.
If a TLS server receives a ClientHello containing a version number greater than the highest version supported by the server, it MUST reply according to the highest version supported by the server.
For example, if the server supports
TLS 1.0, 1.1, and 1.2, and client_version is TLS 1.0, the server will proceed with a TLS 1.0 ServerHello. If server supports (or is willing to use) only versions greater than client_version, it MUST send a “protocol_version” alert message and close the connection.
TLS 1.0, 1.1, and 1.2, and client_version is TLS 1.0, the server will proceed with a TLS 1.0 ServerHello. If server supports (or is willing to use) only versions greater than client_version, it MUST send a “protocol_version” alert message and close the connection.
Whenever a client already knows the highest protocol version known to a server (for example, when resuming a session), it SHOULD initiate the connection in that native protocol.
I’m sure there are several other founctions and difference more than this, for more information on TLS protocol Attributes & functions you can refer RFC5246.

What is RAMPAGE Attack? Why Does It Affect Every Android Since 2012?
No matter how secure Google calls its mobile operating system, it seems like a determined security researcher could come up with a vulnerability any day. A team of eight researchers has done the same with their exploit having a fancy name RAMPAGE (CVE-2018-9442), which enables unauthorized access to Android devices.
What is RAMPAGE attack?
In 2012, with the release of Android ICS, Google introduced a new component to the Android kernel called ION that allocates memory for different apps and services. RAMPAGE targets ION, thus, making itself a threat to millions of Android devices across the world.
However, Android isn’t to be blamed entirely. The attack originates out of a fundamental, more of a hardware error in the RAM chips called Rowhammer which works on ARM-based devices. In modern RAM chips, the memory cells are packed very close to each other. This could result in the cells leaking their charge and interact with other cells.
Each memory cells contains one memory bit which represents a unit of data in the RAM chip. An attack leveraging row hammer can be used to extract data from the RAM chip by changing the state of a memory bit from 0 to 1 and vice-versa, i.e., bit flipping.
How does RAMPAGE work?
A malicious app fitted with RAMPAGE can use the ION memory subsystem and cause a row of memory bits to change its state repeatedly until bit flipping happens in the adjacent row.
This way, an app could potentially attain admin level privileges to access the data of some other app which is not possible in regular scenarios. It can harvest confidential information like passwords from a password manager or browser, documents, photos, messages, etc.
“RAMPAGE breaks the most fundamental isolation between user applications and the operating system. This attack allows an app to take full administrative control over the device,” wrote the researchers on the website describing the attack.
Does it affect my device?
As mentioned above, every Android 4.0 and above devices released since 2012 that use LPDDR2, LPDDR3, or LPDDR4 RAM chip come under the radar. Although it’s not confirmed the attack could be crafted for iOS, Windows, MacOS, and also cloud servers.
However, the story isn’t as scary as it sounds. Modern operating systems don’t write all the information about an app in adjacent memory cells; it’s scattered across different cells. So, the process of flipping the bits may be easier but knowing what’s written on the memory bit isn’t.
An average Android smartphone with 32GB memory capacity has 32 billion bits. Given this fact, it would be nearly impossible for an attacker to pinpoint a particular piece of information. It’s nothing but a game of chance.
What should I do?
You can sit back and try not to worry. Google and Amazon are already notified about the RAMPAGE so it’s less likely that some malicious app would appear on Google Play. Moreover, it’s not known if the vulnerability is being exploited in the wild.
How do I check whether my device is vulnerable to RAMPAGE?
If you want, you can check whether your device is vulnerable to RAMPAGE by using the test app [direct link] created by the researchers. They have also created an app called GuardION which is meant to prevent attacks from modifying the memory cells.
It’s not the first time we have seen attack methods trying to explore hardware errors. In a similar attempt, a row hammer based attack called DRAMMER appeared in 2016 that affected Android devices.
Back then, there was a sense of satisfaction as it was less effective on LPDDR4 memory, but this doesn’t seem to be the case with RAMPAGE. Hopefully, devices makers and Google would come up with security patches soon.
