Métodos mais eficazes para proteger dados no Excel 2019
O Microsoft Excel 2019 é uma ferramenta poderosa para a manipulação e análise de dados. No entanto, com o aumento das preocupações relacionadas à segurança de dados, é essencial que os usuários adotem práticas eficazes para proteger suas informações sensíveis. Este artigo aborda as maneiras mais eficazes para garantir a segurança dos dados no Excel 2019, ajudando a prevenir acessos não autorizados e a proteger a integridade das informações.
Proteção com Senha
A primeira linha de defesa para proteger seus dados no Excel 2019 é a utilização de senhas. O Excel permite que os usuários apliquem senhas a arquivos inteiros, folhas de trabalho individuais e até mesmo células específicas. Here is more information regarding veja a seguir look into our webpage. Aqui estão alguns passos para implementar essa medida de segurança:
Proteção de Arquivo
Proteger o arquivo com senha impede que usuários não autorizados o abram. Siga os passos abaixo para proteger um arquivo:
Abra o arquivo Excel que deseja proteger.
Clique em Arquivo > Informações.
Selecione Proteger Pasta de Trabalho e, em seguida, Criptografar com Senha.
Digite uma senha e clique em OK.
Confirme a senha e clique em OK.
Proteção de Planilha
Proteger planilhas individuais pode ser útil quando várias pessoas têm acesso ao arquivo, mas não devem modificar determinadas folhas. Para proteger uma planilha:
Abra a planilha que deseja proteger.
Clique com o botão direito do mouse na aba da planilha e selecione Proteger Planilha.
Digite uma senha e defina as permissões que deseja conceder.
Clique em OK.
Restrição de Acesso
A restrição de acesso permite que você controle quem pode visualizar ou editar o conteúdo do seu arquivo Excel. Existem duas abordagens principais para implementar isso no Excel 2019:
Controle de Permissões
O Microsoft Excel oferece a possibilidade de definir permissões específicas para diferentes usuários. Isso pode ser feito através das opções de compartilhamento do arquivo:
Clique em Arquivo > Compartilhar.
Selecione Convidar Pessoas e adicione os endereços de e-mail dos destinatários.
Defina as permissões como Pode Editar ou Pode Visualizar conforme necessário.
Proteção com Azure Information Protection
Para empresas que utilizam o Microsoft 365, o Azure Information Protection (AIP) é uma ferramenta poderosa para proteger documentos confidenciais. Com o AIP, você pode aplicar etiquetas de segurança que controlam o acesso ao documento:
Instale e configure o cliente do AIP.
Abra o arquivo Excel e selecione Proteger > Restringir Acesso.
Escolha a etiqueta apropriada, como Confidencial ou Somente para a empresa.
Criptografia de Dados
A criptografia de dados é uma forma robusta de proteger informações sensíveis no Excel. A criptografia garante que, mesmo que um arquivo seja acessado por alguém não autorizado, os dados permanecerão inacessíveis sem a chave de decriptação.
Criptografia de Arquivo
O Excel 2019 permite criptografar arquivos, tornando-os inacessíveis sem a senha correta. Este processo foi descrito anteriormente na seção de proteção com senha.
Criptografia de Dados Sensíveis
Para dados particularmente sensíveis, considere a utilização de software de criptografia de terceiros que possam adicionar uma camada extra de segurança aos seus arquivos Excel.
Uso de Macros Seguras
Macros podem ser úteis para automatizar tarefas no Excel, mas também podem representar um risco de segurança se não forem usadas corretamente. Aqui estão algumas práticas recomendadas para garantir a segurança ao usar macros:
Habilite macros apenas de fontes confiáveis.
Assine digitalmente suas macros para garantir sua autenticidade.
Revise e edite macros manualmente antes de executá-las.
Backup Regular
Fazer backup regular dos seus arquivos Excel é uma prática essencial para garantir a integridade dos dados. Em caso de perda de dados, corrupção de arquivo ou acesso não autorizado, um backup recente pode ser crucial para a recuperação das informações.
Configure backups automáticos utilizando o OneDrive ou outro serviço de armazenamento na nuvem.
Mantenha cópias de segurança em dispositivos externos, como discos rígidos ou pendrives.
Monitoramento e Auditoria
Monitorar o acesso e as alterações aos arquivos Excel pode ajudar a identificar atividades suspeitas ou não autorizadas. O Excel 2019 e o Microsoft 365 oferecem ferramentas para auditoria e monitoramento:
Utilize o Histórico de Versões para rastrear alterações feitas no arquivo.
Ative notificações de atividade através do OneDrive para ser alertado sobre acessos e edições.
Conclusão
A proteção de dados no Excel 2019 requer uma abordagem multifacetada que inclua proteção com senha, restrição de acesso, criptografia, uso seguro de macros, backups regulares e monitoramento contínuo. Ao implementar essas práticas, você pode garantir que seus dados permanecem seguros e protegidos contra acessos não autorizados e ameaças potenciais. A segurança dos dados deve ser uma prioridade contínua para qualquer usuário do Excel, e as ferramentas e técnicas discutidas aqui são essenciais para alcançar esse objetivo.

What Are "Business" Notebooks?
Business-class notebooks (Dell Latitudes, Lenovo ThinkPads,
HP EliteBooks, to name a few) differ from consumer notebooks in several important ways.
Warranty/Support: business support is completely separate from normal consumer-level support.
It has better response times (especially
when shipping out parts or replacement systems) and is domestic.
Build Quality/Design: unlike the 99% of consumer notebooks constructed of plastic, business notebooks include a stronger metal internal
support structure to prevent wear and tear on the circuit boards.
Additionally the notebook's exteriors are more industrial and thankfully absent of
glossy plastic.
Ports: business notebooks include quite a bit more than the bare essentials.
Most come with an ExpressCard slot for adding
additional ports. Furthermore they often include DisplayPort
over HDMI and a legacy VGA port. Some larger business notebooks even have serial ports for
connecting to legacy hardware
Wireless: business notebooks include beefed-up wireless connectivity.
This includes but isn't limited to additional reception antennas, better antenna placement,
and higher-end wireless cards (such as the Intel 6200/6300 series).
Battery Life: extended batteries and battery slices aren't often found on consumer notebooks; they are however an option on most business
notebooks. They can extend battery life up to 50-100% compared to
just the standard battery.
Optical Drives: IT departments continue to use
optical drives for loading software, imaging, and data
transfer. While consumers might have left the technology behind in favor
of online downloads, businesses will take longer to get
to that level.
Anti-glare Screens: glossy-surfaced screens are not practical to use in well-lit environments like offices;
anti-glare/matte coatings make a lot more sense.
Operating Systems: Windows 7 Professional is the OS of choice for
business notebooks - "Home Premium" isn't found on corporate fleet notebooks.
The Lenovo ThinkPad T420 and Dell Latitude E6420 we're looking at today
are "true" business notebooks. That is, they are top-end models with all the available
bells and whistles. Some notebooks are billed as "business class" but are really little more than consumer laptops with better
warranty support; examples include the Dell Vostro series, HP ProBook,
and lower-end Lenovo ThinkPads. They're constructed of mostly plastic and are missing a lot of the features mentioned above
such as better port selection and wireless connectivity, extended battery options, optical drives, and the Windows 7 Professional OS.
Design and Build Quality
While the purpose of business notebooks isn't to look good on a
display shelf, I've yet to see anyone complain about a good-looking design. ThinkPads look generally the
same as they have looked since they were introduced
about 20 years ago. The Dell Latitude line has evolved quite a bit however;
this latest-generation E6420 has a classy design with a contrasting color scheme.
Another plus for the Dell is its all-metal exterior; the ThinkPad's exterior is all plastic.
The ThinkPad has just as much structural integrity
though thanks to its internal metal support structure.
Nonetheless the edge goes to Dell.
Screen
Both notebooks come standard with a lowly 720p resolution however our T420 has the upgraded 1600x900 resolution (900p),
which has about one-third more space than 720p. This equates to a lot more working
room and the ability to use two windows side-by-side.
Additionally the 900p display is noticeably more colorful than and not as cold as the Dell's 720p
display. The T420 wins this round as configured but in reality it's
a tie since both notebooks can be configured the same.
Keyboard and Touchpad
I like the light and accurate feel of the E6420's new keyboard;
despite this the ThinkPad's still has the edge in tactile feedback.
Additionally the T420 has a better layout; the delete, home, end, pgup, and pgdn keys are nicely arranged in a square at the upper right.
The E6420 has an ace up its sleeve - it has available keyboard backlighting and the T420 doesn't (it still uses the functional ThinkLight above the keyboard however).
Despite the lack of backlighting the edge here goes to the T420.
The touchpad is another area of contention; the touchpads themselves are both excellent but the ThinkPad's
pointing stick is has a more familiar feel and is more accurate.
Again the edge overall goes to the T420.
Weight and Battery Life
The T400 series ThinkPad has always weighed within a few tenths;
the T420 comes in at a rather light 5.34 pounds with
the extended 9-cell and manages almost 10 hours
of life. The E6420 is much heavier at seven pounds and has an hour less battery life with
its extended 9-cell.
Speakers
Generally these aren't a concern on a business notebook but the
T420's speakers are utterly weak and the E6420's are positively amazing
(for a notebook); they sound full and get
loud enough to fill a small room.
Other Differences
The T420 and E6420 are evenly matched aside from the items we've discussed thus far.
There are some differences with the included ports: the E6420 has HDMI and a SmartCard reader whereas the
T420 has DisplayPort and mini-Firewire. Their overall performance is comparable; both include dual-core Intel i5
processors, 4GB of RAM, and 7200RPM hard drives.
The Winner?
The Lenovo ThinkPad T420 takes home the trophy. The keyboard and touchpad
are ever so slightly better; it weighs a lot less (5.34 lbs.
vs. 7 lbs.), gets an hour more battery life
and still comes in slightly cheaper. Having said that, I personally wouldn't
have a problem using either notebook on a daily basis.
The price of these notebooks will vary depending on many factors including the time of year and available coupons.
Also don't forget to check out the companies' outlet stores for refurb and restocked units; these notebooks can often be had for
several hundred less than retail. Go for whatever one costs less but if it's
too close to call, we'd go with the ThinkPad T420.
